Priority Part II - put this whole game a step further.

If I forgot about some rules, please don't cut my head off... ^^

Since there was no sticky thread 'how can I contribute' or 'how can I bring an article online', I was so free and just started this thread..

This will also find it's way to the Judge-List Lv3, but I'm afraid all the cool guys that hadn't had the chance to write and pass the Lv3 test would have no chance to contribute.

Therefore, I'll also post this article here.

This is a translation of my GERMAN article, please don't mind my bad English.

soul :cool:

-------------------------

As we all know, there's already a very good article about Priority (see the article by Helpoemer316 located at http://www.cogonline.net/threads.2229&highlight=Priority), but still, I've writen another one.
The other article outlines the important situation when a monster was summoned to the field, but there are some other situations where Priority can become VERY important and this is not covered in the other article.
The question is how we should handle a situation like that one I stumbled across on a tournament last weekend:

Player A controls a face-up Jinzo.
Player B has got a face-down Call of the Haunted.

Player A normal summons Tsukuyomi, targeting his Jinzo with its effect.
Player B can't chain Call of the Haunted, because Jinzo is still face-up on the field.

Now the Chain resolves and Jinzo is face-down.
After this happened, the players had a question and called for a judge. One player appealed, so I came to the table. To keep it short, the question was:
I forwarded the question to Steve Okegawa and he forwarded it to Kevin Tewart, but the answer was a short "˜there is no answer'. *lol*
So there's only one chance to take the game to another level (as some guys at the Empyre Group use to say):
Come up with a theory based on facts which turns out to be right (or maybe not, but we're optimistic). ^^

1st fact:

There has been a question on Judge List: http://lists.upperdeck.com/read/messages?id=3127#3127


QUESTION:
Player A activated The Warrior Returning Alive and got back Black Luster
Soldier - Envoy of the Beggining for the graveyard.

Player B activated Mind Crush in response to the Black Luster Soldier - Envoy of
the Beggining being put in Player A's hand, calling Black Luster Solder - EOTB.

So my question is, are you allowed to respond to a movement like adding a card
to a hand? Also does Plaer A have Priority to summon BLS - EOTB before Player B
activates Mind Crush?

-------------------------------------------------------------------------------

ANSWERS:
1. Yes you can respond.
2. No the player doesn't have priority to Special Summon his monster.

This Ruling tells us that the Turn Player does NOT have Priority (to summon a monster).
Before we start concentrating on this special example, I'll show you another one:

Player A activates Graceful Charity. He draws 3 cards and discards 2 cards from his
hand to the Graveyard.
Player B wants to respond with his set Appropriate. Assuming, the Turn Player COULD use Priority to summon a monster, he would change the Game State and so his opponent would have no chance to activate his set Appropriate.
Appropriate's activation condition would not be given anymore.

Sounds good, right?

So how can we reconcile the statement "˜the Turn Player has ALWAYS Priority' and the facts I've just shown you?
It's really easy, because we'll subclassify Priority.


The difference:

(Information: So far this article only consisted of facts. So this is where the fun begins, because we start with the theoretical part. All ideas explained in the following lines are NOT officially confirmed, but since we're used to using not confirmed statements, this shouldn't be all too shocking for you.)

There are 2 subclasses of Priority. We'll call the first one Effect Priority, the second Action Priority.
Let's have a deeper look at them"¦


Effect Priority

After the Summon of a monster, the Turn Player gets Effect Priority. Effect Priority means that the player is allowed to use the effect of a face-up card on his side of the field, activate a Spell Speed 2 effect or an optional Trigger effect, if the Timing is correct.

Some examples:
  • The Turn Player summons Exiled Force
    -> He has Priority and can activate its effect with Effect Priority before his opponent can respond to the summon (in this case he uses the effect of a face-up card on his side of the field)
  • The Turn Player summons Mobius the Frost Monarch and activates its effect
    -> He uses an optional Trigger Effect, since the Timing is correct
  • The Turn Player summons Sinister Serpent and responses to the summon with his set Torrential Tribute
    -> He activates a Spell Speed 2 effect after the summon with his Effect Priority
If the player uses his Effect Priority and activates a proper effect, he does NOT change the Game State. So the "˜last thing happened in the game' is still the same, even after he used his Effect Priority.

If this would not be true, he could use Priority to activate a Normal Spell Card after the summon of his monster and so his opponent would have NO CHANCE to respond to the summon of the monster (cause the Game State changed already and Torrential or whatever card he wanted to activate would have missed its Timing).

Effect Priority is what you're allowed to do as described in Michael's article.


Action Priority:

When a player uses his Action Priority, he can change the Game State. If the player summons a monster, he uses his Action Priority. He could also use Action Priority to activate an effect, etc.
Therefore, Action Priority is ~ stronger ~ than Effect Priority. You can do all the things you're allowed to do when you have Effect Priority PLUS you can make some cooler moves like activate a Normal Spell Card, summon a monster, stuff like that.

Let's kick this another step further and come up with some hard allegations:

1st)
The Non-Turn Player NEVER gains Action Priority.
(If you would be used to reading articles I wrote (which shouldn't be the case, cause you don't understand German :p "¦ Well.. Scott Elliot could be used to, he told me that he can understand German. ^^), these "˜hard sounding' punch lines are like signature lines in my articles. ^^)
If we think about that for same time, this will become all too clear. The Non-Turn Player NEVER has the chance to summon a monster during the opponent's turn. The Non-Turn Player NEVER has the chance to activate a Normal Spell Card or set a card during the opponent's turn.
If he's allowed to do something like that, it's always the outcome of an EFFECT. Ultimate Offering gives the Non-Turn Player the chance to summon a monster during the Battle Phase of the opponent. Dust Tornado allows the Non-Turn Player to set a Spell or Trap Card during the opponents turn.


2nd)
After the Turn Player used Action Priority and after the complete resolution of the chain (started with a response after the action of the Turn Player), the Turn Player retains EFFECT Priority. So the Turn Player does NOT retain Action Priority! If he would retain Action Priority, he could change the Game State before the opponent could respond to the 1st action.

An example:

The Turn Player uses Action Priority to activate Premature Burial in order to summon Tribe-Infecting Virus.
The opponent does not want to chain.
After the resolution of the chain, the Turn Player wants to summon another monster. If he would be allowed to do so, the opponent would have had NO chance to respond to the special summon of Tribe-Infecting Virus.
So the Turn Player only gains EFFECT Priority after the resolution of the chain. He can now activate the effect of Tribe-Infecting Virus but he can NOT activate a Normal Spell Card or summon another monster.

The Game State doesn't change when the Turn Player uses Effect Priority, so the opponent ALWAYS has the chance to respond to the last action happened in the game and so he'll NEVER miss the Timing.

If the Turn Player passes EFFECT Priority after the resolution of a chain, the opponent gets Priority. If he also passes Priority, both players have passed and therefore, the Turn Player gets ACTION Priority again. Now he's allowed to activate a Normal Spell Card or summon a monster, stuff like that..
If the Turn Player passes Action Priority and the opponent also passes, the game continues with the next Phase.

Now the bottom line of this article, the example mentioned at the beginning:

Player A controls a face-up Jinzo.
Player B has got a face-down Call of the Haunted.

Player A normal summons Tsukuyomi, targeting his Jinzo with its effect.
Player B can't chain Call of the Haunted, because Jinzo is still face-up on the field.

Now the Chain resolves and Jinzo is face-down.

After the complete resolution of the chain, Player A retains EFFECT Priority.
He doesn't want to use it and therefore, he has to pass Priority.
Therefore, Player B has Priority and can activate Call of the Haunted targeting a
random Monster (doesn't really matter right now ^^).

The new chain resolves, the monster is summoned to the field and Player A retains Effect Priority again. If he doesn't want to use it and if Player B would also pass Priority, Player A would retain ACTION Priority.
Now he would be able to flip-summon Jinzo or do some other cool things"¦


Sorry that this article is so long (in fact, it's shortened, the German version is longer"¦ ^^).
Please don't mind my bad English, I hope that I could contribute and you all understood what I meant. o_O

Very nice article. It uses fact and clear, concise descriptions of one of the most confusing aspects of this entire game. I like it very much.
 
Excellent work. It is very logical and helpful. In the absence of an "Official" essay I would say this should be a good solid position to make rulings from.

Of course the true question that could still go either way is that muddy part after Tsukuyomi has resolved and whether the turn player does have the right of "effect priority" or does the the non-turn player have first right to "respond" to the last "fact" of the game. I am inclined to agree with your article that "Effect Priority" makes more sense.

Thank you a lot.
It would be great if you could tell me how you felt about the language used. I guess it's 'easy English' in your eyes, because it's 'just' translated... ^^

Well, someone in Germany came up with 'why writing all this stuff when there is no official essay???'

My answer is that we judges have to act in a way WE think is the correct one. If there are no official guidelines, we have to think ourselves what would be the most correct solution.

If someone sees the article from this point of view, it shines in a very different light. ^^

I can only speak for me, but when I will be in the position again, that I had last weekend, I KNOW how to handle it. :)

Of course the true question that could still go either way is that muddy part after Tsukuyomi has resolved and whether the turn player does have the right of "effect priority" or does the the non-turn player have first right to "respond" to the last "fact" of the game. I am inclined to agree with your article that "Effect Priority" makes more sense.

At least it doesn't make that much of a difference. Even if the Non-Turn Player would be the FIRST one to respond to the changed Game State, he would not be able to CHANGE the Game State and so every player will have his chance to respond to it in the chain. :)

But because an Ignition Effect and a summon have a lot in common (you can only start it in you Main Phase, and so on...), I guess that the rules that apply after a summon of a monster (the Turn Player has EFFECT Priority) should also apply after the resolution of a whole chain.

I left this part out, but maybe I should make some additional comments. What do you think? ^^

soul :cool:
 
Sorry for double-posting, but it's the better way... :)

There was a reply from Kevin Tewart with no new information and a lot of criticism... :(
But then there came a reply from Daniel Scheidegger, that is very helpful. ;)

----------------------------

I think you are complicating things far more than they need to be, and I
question the authenticity of Kevin saying "there is no answer", unless
that email is very old - because there is an answer and its easy.

So in your example is Player A's Main Phase, so he starts with the
Priority (it is his turn after all).

He Summons Tsukuyomi. Its trigger effects starts a chain. (After a
Summon player A would normally retain priority to activate an Ignition
Effect or Spell Speed 2 Spell or Trap, but Tsukuyomi's Trigger Effect
must start a chain).

He targets Jinzo. The opponent may chain an effect, but does not. The
turn player may chain an effect, but does not.

Jinzo is flipped face-down.

Priority is now passed to Player B.

Player B activates "Call of the Haunted". Neither player chain anything,
and Player B finishes his Special Summon.

Priority is passed pack to Player A. He Flip Summons Jinzo. Since he
just performed a Summon, he retains priority only to activate an
Ignition or Spell Speed 2 Spell or Trap. If he decides not to activate
one of those kind of effects - Priority passes to Player B.

Do you see how priority is passed back-and-forth between the players,
with the only hiccup being when the turn player performs a Summon.

It's not as complicated as everyone makes it out to be - and there is
only 1 kind of priority.

Seems to be easier than expected...
And whatever Mr. Tewart says, this article has been useful because now I know how it works... :)

I think that's pretty good... ^^


soul :cool:
 
My article is very outdated (I wrote it about this time last year, so yeah... things change over time, but that's the way YGO seems to work) so I had sort issued a subliminal challenge awhile back for someone to step up and write a second updated version, I'm glad Oli here could do that.

Very nicely written... There's always been a controversy surrounding priority and what it's place is in YGO, and the problem with the game that Konami created is that there is and will never be any set in stone explanation of how everything actually works. This is about as consistent as it gets and that's a very sad and moot point at this time I guess.

But yeah, well written, very informative, but I wouldn't expect anything less from Oli here.
