Agath, Fire Plane Duque

Eminence — Whenever you tap a land for mana,
if Agath is in the command zone or on the battlefield, you may pay {1}. If you do, copy the next red sorcery spell you cast this turn. You may choose new targets for the copy.

Indestructible, Flying

As long as your devotion to red is less than 7, Agath isn't a creature.
