Twilight Drover + Illusionist's Bracers + Ashnod's Altar + Chromatic Orrery

Twilight Drover

Illusionist's Bracers

Ashnod's Altar

Chromatic Orrery

How it works

1. Activate Twilight Drover by paying 3 and removing a +1/+1 counter from it.
2. Illusionists's Bracers triggers, copying Twilight Drover's ability.
3. Resolve both Twilight Drover abilities, creating four 1/1 Spirit creature tokens.
4. Activate Ashnod's Altar twice by sacrificing two Spirits, adding CCCC.
5. When the Spirits die, Twilight Drover triggers twice, putting two +1/+1 counters on it.
6. Repeat.

This loop transforms Twilight Drover into an unstoppable engine by leveraging the passive duplication granted by Illusionist's Bracers. When you activate Twilight Drover to generate tokens, the Bracers automatically double the output, and Ashnod's Altar converts those sacrificed tokens into the raw mana needed to fuel the next activation while easily funding the costs. Meanwhile, Chromatic Orrery ensures that the colorless mana produced by the Altar can be filtered into any color you might need to keep the cycle going. Each iteration leaves you with a net surplus of tokens, counters, and mana, resulting in an infinitely large creature alongside boundless resources.
