Dr. McCoy, Surly Surgeon

Mana cost: {2}{W}{W}

Legendary Creature — Human Doctor

When Dr. McCoy enters, put a +1/+1 counter on another target creature you control. If another creature you control with a +1/+1 counter on it would be destroyed, instead remove all +1/+1 counters from it and all damage already dealt to it is healed.
