Saheeli, the Gifted — Commander 2018 #44

+1: Create a 1/1 colorless Servo artifact creature token.

+1: The next spell you cast this turn has affinity for artifacts. (It costs less to cast for each artifact you control as you cast it.)

−7: For each artifact you control, create a token that's a copy of it. Those tokens gain haste. Exile those tokens at the beginning of the next end step.

Saheeli, the Gifted can be your commander.
