Kable, Redstone Ascended

As long as your devotion to red, and blue is less than nine, Kable isn’t a creature.
(Each {r} and {u} in the mana costs of permanents you control counts toward your devotion.)

Whenever you cast an artifact or enchantment spell, create a 2/2 colorless
“Redstone Construct” artifact creature token with "
When this creature dies, deal 2 damage to any target."
