Von Flop, King of the blue

When Von Flop enters, you become the monarch.

Sea creatures you control have Islandwalk, if
they already have Islandwalk, they get +2/+2
instead. (Creatures with the subtype Cephalid, Crocodile, Fish, Homarid, Jellyfish, Leviathan,
Oyster, Serpent, Shark, Squid, Starfish, Turtle,
Kraken, or Whale are considered sea creatures.)

{1}{u}: Target opponent gains control of an Island
you control until the end of their next turn.
