Percy Jackson

Islands you control give {u}{u}.
Whenever you cast a blue spell or an island, put a
+1/+1 on all blue creatures you control. Percy
Jackson gains indestructible, menace, double
strike, hexproof, trample and +3/+3 until end of
turn.
{u}{u}, tap a blue creature you control: search
your library for an island and put it onto the battlefield tapped.
