Card text says:
"At the beginning of the combat on your turn: Target creature you control loses a reinforcement. Then: Destroy the top X cards of your library. X is that creature's power."
It actually functions as: "At the beginning of your turn: Target creature you control loses a reinforcement."
However, it only destroys the top X cards if you target a nontoken creature. If you target a token stack, it doesn't destroy any cards.
It also seems to be destroying base power instead of creature's power.
Is this intended?
