I've never heard it called that. It's time-stamping. The newest effect rules.So it's a grandfather priority issue.
That's what I figured too but I wanted to see if there were any unpublished official rulings yet.
Yeah, but they're not consistent with it. The only cards I know of that have "This card inflicts Piercing Battle Damage" are ones from mini-sets, such as those Duelist Packs. It's not catching on. And I suppose they don't want to add new terminology to the game in case people don't know what they're on about (but that's sometimes the case anyway). Keep things simple and obvious for the kiddies, who of course are the only ones who play this children's card game.My own thought is that they let some geeks in on this since we like that term a lot and it instantly rung a bell with me.
As for trample, I think I've seen some cards refer to it as "piercing" damage now, yes?
The Japanese ruling agrees with Maruno, since both are continuously re-applying themselves.
For example, if Dreadroot is on the field and you summon Gene-Warped Warwolf, its ATK becomes 1000. If you then equip it with Axe of Despair, its ATK becomes 1500.
