Hinjax, Aspect Breaker

Indestructible
As long as your devotion to green, white, and blue is less than ten, Hinjax isn't a creature.
Whenever Hinjax or another nontoken creature enters the battlefield under your control, another target creature you control gains your choice of forestwalk, mountainwalk, islandwalk, plainswalk, or swampwalk until end of turn.
