Ok, so to help clear this up, once and for all (maybe).
From the old Netrepâ„¢ 6.0 files:
"
Horn of Heaven" may only be used to negate the Summon of a monster that is being Summoned through its own effect, like that of "
Gate Guardian", "
Dark Necrofear", etc."
"
Horn of Heaven" may not be used to negate the Special Summon of a monster being Special Summoned through the effect of another card."
This is how I understood these.
The 1st ruling was referring to cards that were basically 'Special Summon only' type cards, MEANING, the ONLY way they could be summoned initially, was by Special Summon, usually the monsters required you to remove x-cards from your Graveyard to Special Summon them.
I, and apparently several other people, did not classify monsters like "
Vampire Lord" and the "Phoenix" with these because it was their EFFECT that summons them back, NOT how they were summoned in the first place.
The 2nd ruling I think everybody agrees on, you can't use "Horn" or "SJ" on monsters brought back by "Call", "Premature", etc..
Now, THIS is where I had the monsters like "
Vampire Lord" and the "Phoenix" classified becuase it was their EFFECT that was bringing them back, not a condition of their initial summoning.
But you are now saying that monsters like "
Vampire Lord" and the "Phoenix" should be 'lumped' into the same category as monsters like "
Chaos Sorcerer", "
Fenrir", etc..?
And as such, becuase they are being brought back by an effect generated/activated within 'themselves', not considered an outside effect like "
Premature Burial", then both "
Horn of Heaven" and "
Solemn Judgment" can be used to negate that Special Summoning?
To re-iterate, I'm asking for clarification on this.
Thanks.
