Mycosynth Lattice + Krark-Clan Ironworks + Kellan, Daring Traveler // Journey On + Temur Sabertooth

Mycosynth Lattice

Krark-Clan Ironworks

Kellan, Daring Traveler // Journey On

Temur Sabertooth

How it works

1. Cast Journey On either from your hand or from the command zone by paying 1 and commander tax, if applicable, creating at least three Map artifact tokens and exiling Journey On with the ability to cast it from exile.
2. Activate Krark-Clan Ironworks by sacrificing three Maps, adding six C.
3. Cast Kellan from exile by paying 2.
4. Activate Temur Sabertooth by paying 2, returning Kellan from the battlefield to your hand.
5. Repeat.
6. Once you have infinite mana, you may forego sacrificing the Maps, and you may use the Maps to put infinite +1/+1 counters on creatures you control.

This clever loop gets its engine running thanks to Mycosynth Lattice, which turns every single permanent into an artifact so they can be fed directly into Krark-Clan Ironworks for generous chunks of colorless mana. With that financial backing, you cast Kellan, Daring Traveler from exile—having previously sent him there via Journey On while generating a bounty of Map tokens—and then bounce him right back to your hand using Temur Sabertooth's activation. Because Mycosynth Lattice also smooths out your mana colors, you can easily sustain the Sabertooth's activation cost and repeat the cycle to generate infinite mana and endless loops of Kellan entering and leaving the battlefield.
