Arsnex, Goddess of Change

Indestructible
At the beginning of your upkeep another target creature becomes a 1/1 blue frog with no abilities, a 2/1 black shade with deathtouch, or a 4/4 green boar with trample until end of turn.
As long as your devotion to Blue, Black, or Green is less than 8 Arsnex, Goddess of Change is not a creature.
