Who me?
I think bouncing it is a red ability, but it should involve the flipping of a coin.
Moreover, he has only one power so he is never going to survive combat without help. I would make it something like: "Whenever ~this becomes blocked, flip a coin. If you win the flip, destroy the blocking creature. If you lose the flip, return ~this to owner's hand"
This seems more of a red kinda card..
