Coralhelm Tidebringer

Coralhelm Tidebringer's power is equal to the
number of Islands you control.

Whenever Coralhelm Tidebringer attacks,
create an X/X blue Elemental Island creature
token with hexproof, trample, and vigilance
that's attacking, where X is Coralhelm
Tidebringer's power. Sacrifice that token at
the end of combat.
