Awaken the Depthkin

When Awaken the Depthkin enters the battlefield, shuffle up to three target cards from your graveyard to your library, then scry 3.
Defile 6 — Whenever exactly six cards are put into your graveyard from anywhere, if Awaken the Depthkin isn't defiled, it becomes defiled and you create an 8/8 blue Octopus creature token.
