When this creature enters, exile target creature an opponent controls until this creature leaves the battlefield.

Islandwalk (This creature can't be blocked as long as defending player controls an Island.) Whenever this creature attacks, you may exile target creature defending player controls until this creature leaves the battlefield. (That creature returns under its owner's control.)

This creature enters with X +1/+1 counters on it, where X is the amount of life you've gained this turn.
