I agree with wildhorn.
However, if you are using a temple of asyra to spawn creatures and waiting for the opponent to approach you it might be an ok move... Very situational though. Kinda like a one time use meditation amulet without an initial investment cost.
Edit: in academy, combined with the priestess ability, this card is a variation of [mwcard=MWSTX2FFI06]Defend[/mwcard].
Edit 2: In the same spirit as above, the arena priestess can use it to gain 2 mana and get 1 life. This is not that bad of a move if you have nothing better to do.
