Davio, Cunning Outlaw

Flash, Haste, Deathtouch
You may cast Assassin spells as though they have
flash.
Assassins you control enter the battlefield with
your choice of a haste or a deathtouch counter.
Whenever the ability of an assassin you control
causes one or more creatures to die, put a +1/+1
counter on Davio and draw a card.
