Red Hare

Soulbond (You may pair this creature with another unpaired creature when either enters the battlefield. They remain paired for as long as you control both of them.)
When Red Hare enters the battlefield, if you do not own it, sacrifice it.
As long as Red Hare is paired with another creature, both creatures get Vigilance and First Strike. If the other creature is a Warrior, both creatures can't be blocked.
