Halagash, God of Reflections

Flying, Indestructible
As long as your devotion to blue and black
is less than seven, Halagash isn't a creature.
Whenever a nontoken creature enters the battlefield under your control, you may pay {u/b}{u/b}{u/b}. If you do, create a token that's a
copy of it.
Other creatures you control have Flying and Indestructible.
