The 4 combo pieces

What must be in place

Kaya has at least two loyalty counters on it.

How to execute it

  1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
  2. Activate Retrofitter Foundry's second ability by paying {2} and tapping it, creating two 1/1 Servo artifact creature tokens.
  3. Activate Clock of Omens by tapping the Servos, untapping Retrofitter Foundry.
  4. Activate Ashnod's Altar by sacrificing a Servo, adding {C}{C}.
  5. Repeat from step 2.
  6. Once you have infinite mana, you may instead use Retrofitter Foundry's first ability to untap it and get infinite untapped Servo tokens.
