Starfish Prime

Krakens, Leviathans, Serpents, Starfish, and
Whales you control get +1/+0 and have flying.
Whenever a creature enters the battlefield under
your control, scry 1, then surveil 1.
At the beginning of your end step, create X 0/1
blue Starfish creature tokens, where X is the
number of Starfish you control.
