TU also doesn't imply it copies all previous effects that happened to a creature. If it did TUing a Phoenix would make an Otyugh grow for every time it was devoured. TU should copy of the current state of the creature without caring how it got to that state.
Voodoo implies that when something actually happens to it it triggers. Nothing happens to the new copy other than a new copy in state x, and nothing happens to the old copy other than having its current state copied.
I fail to see how any of that would hint that it would deal more damage. The reason damage is dealt is because of the internal mechanisms of the game, not because of something you could logically derive from the wording on either card.
I completely agree with this post. I had seen the builds in my opponents t50 decks and assumed that the combo was to TU before casting gravity pull, letting one run out, and then casting grav pull on the other. I was very shocked to visit the forums and find that you can basically glitch extra damage out of this. I consider the behavior nothing less than an OP exploit, as it is NOT in line with what the cards read.
I haven't read through this entire thread, but consider this the voice of the upper intermediate who doesn't visit the forums often. I did want to respond to one other quote:
Who cares if the card doesnt outright say it, the card also doesnt say that freezing/BB'ing it will freeze the weapon, or that poisoning it will poison you.
This is plain wrong. Voodoo Doll says 'damage
and status'. Poison was the first status effect I thought of when I saw that text. While I wasn't sure initially how freeze would resolve, freezing an opponent's weapon is also implied by the card text.
Perhaps this should move to a bug forum thread, but it does seem more of the traffic is finding its way here.
