The first effect is extremely powerful. It is 1-for-1 at worst, and at best you can trigger the effects of Fabled monsters, or Gusto Grif, or Gem-Knight Obsidian...The list goes on and on. It's simply too good.

The second effect is also very powerful. It has no restrictions and no cost; it's incredibly abusable. Use Giant Rat to search Puddingcess, then bounce Giant Rat.

The last effect is very mean, but acceptable. You wouldn't be able to chain the card because you destroy it as a cost, but your opponent would.

At least I think you can't. Those should be semicolons, right?

Hmmm... I don't like this. I think there are too many unrelated effects going on and they're all highly crippling for your opponent in whatever situation they're in despite it being the same for both players (unless as mentioned the costs benefit your deck). Its just... I dunno, I really don't like it.
