Really? Is it possible to make a deck illegal by taking someone's enhancement or character from them? For example, the enhancement Praising Him Moon takes a character away from a person's hand. Does this make a deck immediately illegal?
Only if you steal Haman's Plot and then use it against a 50-card deck. Everything else that is "stolen" over the course of the game goes back into its owner's deck afterward.
I agree. If I remember correctly the deck is still legal for the current game if you rip haman's plot in a 50 card deck, but is not legal to begin a new game with. Therefore, other enhancements such as Praise Him Moon would not make the deck illegal.
