Oceanic Mershark

Frenzy 2: (Whenever a Cardname attacks and
isn't blocked, it gets +2/+0 until end of turn.)
Oceanic Wereshark cannot attack an opponent
that does not control an island.
Stuck Most-shark, it makes sense that everything that
shunned deep water remains ignorant of their existence.
But their bite gave birth to Jaws with legs."
