How it works
If Runaway Steam-Kin has three or more +1/+1 counters on it, activate Runaway Steam-Kin by removing three +1/+1 counters from it, adding .
Activate Cormela by paying 1 and tapping it, adding that can only be spent to cast instant or sorcery spells.
Cast Demonic Gifts by paying 1, targeting Cormela.
Runaway Steam-Kin triggers, putting a +1/+1 counter on itself.
Resolve Demonic Gifts.
Activate Carrion Feeder by sacrificing Cormela.
When Cormela dies, it triggers twice.
Resolve the first trigger, returning Cormela from your graveyard to the battlefield.
Resolve the second trigger, returning Demonic Gifts from your graveyard to your hand.
Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
Repeat.
This intricate loop centers around casting Demonic Gifts to repeatedly kill and resurrect Cormela, Glamour Thief using Carrion Feeder as a reliable sacrifice outlet. As Cormela repeatedly enters and dies, her death triggers ensure that Demonic Gifts returns straight to your hand while Cormela herself comes right back to the battlefield. Meanwhile, casting that red spell fuels Runaway Steam-Kin, whose counters can be stripped away for red mana to keep the engine running, while Cormela taps to provide the blue and black mana needed for the spellwork. Painter's Servant sits quietly on the battlefield adjusting color identities across the board, tying this colorful brewing experiment into a powerful recursive engine that generates infinite mana, creature tokens, and storm count.
