{cardname}

As long as {cardname} is in your command zone,
you may pay {4}{u}{u}. If you do, you may create a
6/6 blue Leviathan creature token with hexproof.
You may activate this ability only once each turn.
When {cardname} enters the battlefield, return 3
nonland, noncreature permanents to their owner's
hand. Leviathans you control have {u}, {t}: Return
target creature card to its owners hand.
