I have a monster with 3k power and my opponent cast this card (the power of the monster becomes 0 now). After the effects of this card resolves, I cast Gar C’mon and call Garbird. Does the monster (the one currently with 0 power) becomes 3k power because of Garbird or is still 0 power bacause of this card which last for the whole turn.
