Celestial Otter Navigator

Stellar Agility — Whenever Celestial Otter Navigator attacks, you may lose 1 life. If you do, untap it and it gains flying until end of turn.
Cosmic Curiosity — When Celestial Otter Navigator enters the battlefield, look at the top three cards of your library. You may reveal a creature card from among them and put it into your hand. Put the rest on the bottom of your library in any order.

"Among the stars it drifts with grace, collecting cosmic treasures in its playful embrace."{2}{g/u}
