Dixa'n, Princess Qualhunter

Assault (When this creature enters the battlefield, you
may exile it. If you do, you may have it deal damage
equal to its power to any target. If you target a
creature you control this way, the exiled creature deals
damage to it in the form of +1/+1 counters.)
Whenever Dixa'n, Princess Qualhunter deals
damage, create a 1/1 red and green Human
Warrior with assault.
