Displacer Cat

Displacer Cat has trample, haste, and reach.
When Displacer Cat comes into play, it can deal 5 damage to each creature of target opponet's side of the battlefield. If it destroys a creature, exile it instead and give Displacer Cat +1/+1 for each counter for that creature.
If Displacer Cat dies, it gives you life for each counter on Displacer Cat.
