Nadia, The Tidewalker

When Nadia, The Tidewalker enters the battlefield, create a number 3/3 blue Fish,
6/6 blue Whale, and 9/9 blue Kraken tokens
equal to your devotion to blue.
(Each {u} in the mana costs of permanents you control counts toward your devotion to blue.)
{5}{u}{u}{u}: Search your library for a Legendary Creature called Lorthos, the Tidemaker.
You may put it onto the battlefield without
paying its mana cost.
