Icebreaker Kraken

Sacrifice a snow land: remove Icebreaker Kraken
from combat. Its controller scries 2, then draws
a card. You may put an blue Island land token
into play. Any opponent may activate this ability
when they or a permanent they control is
attacked by Icebreaker Kraken. (You can activate
it as well, at any time.)
It carves a path through the frozen seas, feasting on
the creatures drawn or exposed by the trail of open
water.
