This creature can't attack unless defending player controls an Island.
Whenever this creature blocks or becomes blocked by a creature that has been dealt damage this turn, this creature gets +2/+0 and gains trample until end of turn.
When you control no Islands, sacrifice this creature.
The bonus happens when a previously damaged creature becomes a blocker and the bonus is not removed if that creature is removed from the blocking situation by any means.
