Dr. Douglas McMourning

When Dr. Douglas McMourning enters the battlefield, exile target player's graveyard.
For each card exiled this way, put a +1/+1 counter on target creature.
If a card exiled with Dr. Douglas McMourning has flying, creatures you control with +1/+1 counters on them have flying. The same is true for deathtouch, lifelink, first strike, haste, and vigilance.
