Ttaloc, Deity of Wisdom

As long as you control 5 or less islands, Ttaloc,
Deity of Wisdom isn't a creature.
At the beginning of your end step, you may
reveal the top card of your library, if you do,
return all creatures you don't control with
converted mana cost equal than the revealed
cards converted cost to their owner's hands.
