Retrofitter Foundry + Krark-Clan Ironworks + Clock of Omens + Anointed Procession

Retrofitter Foundry

Krark-Clan Ironworks

Clock of Omens

Anointed Procession

How it works

1. Activate Retrofitter Foundry's second ability by paying 2 and tapping it, creating two 1/1 Servo artifact creature tokens.
2. Activate Clock of Omens by tapping the Servos, untapping Retrofitter Foundry.
3. Activate Ashnod's Altar by sacrificing a Servo, adding CC.
4. Repeat.
5. Once you have infinite mana, you may instead use Retrofitter Foundry's first ability to untap it and get infinite untapped Servo tokens.

This loop spins into motion because Krark-Clan Ironworks turns every artifact you control into a mana source, while Anointed Procession supercharges your token generation to double your material at every step. By using Retrofitter Foundry to pump out Servos that are immediately doubled, you create the perfect fuel for Clock of Omens to untap the Foundry and keep the chain going. Every iteration yields a net surplus of mana and bodies, letting you easily transition into making an overwhelming army of constructs or generating infinite colorless mana.
