Cold-blooded Rage

Enchanted creature gains +3/+2 and has First Strike. Attacking does not cause Enchanted creature to tap.
A wounded beast is deadlier than a healthy one.
For in its last throes arise the most brutal and primal instinct, and it is to kill or be killed. It would ignore its pain and unleash its blind and relentless fury. Do not rejoice when a monster is injured, but be cautious.
