A guy I'm talking to about his Mayael the Anima EDH deck came back at me after some advice with this doozy...I'm VERY curious about a ruling on this one, as I've likely misunderstood this from the beginning.
Among other cards he had in his deck were Savageborn Hydra and Serra Avatar. I suggested to him that he drop those two along with some others, as they didn't fit into Mayael's cheaty strategy. His response was to say that Serra Avatar would be kept, as it's P/T is his life total in all zones. I rebutted that this couldn't be true, that until Avatar hits the battlefield, it's P/T is indeterminable(effectively, 0). He states that it MUST be equal to his life in all zones, or else it would be 0/0 as opposed to */*.
I'm thinking I got a pretty good leg to stand on here, but before I push this further, I want a ruling(with rules quote if possible, please)...judge!
