Would {Mutavault} trigger {Champion of the Parish}?

[Keyeto]

I'm afraid not. Animating a land does not cause ETB triggers to go off. This is because there's no actual zone change. It's still the same permanent, it just turns into a creature.

Nope. It's a land. (as you can see from the line in the middle, just below the picture)
It enters as a land. It has an activated ability that makes it a fancy creature.
