Fury Slash Strike

Target creature gains Fury until end of turn.
(When this creature is blocked by a creature with
mana value equal to or greater than it, it gets +2/+2)
If the targeted creature was a balance
enchantment, search your library for a card with "Strike" in it's name and put it in your hand.
Shuffle your library.
My fury bleeds on and it will stop at NOTHING!
