Twilight Drover + Phyrexian Altar + Anointed Procession

Twilight Drover

Phyrexian Altar

Anointed Procession

How it works

1. Activate Twilight Drover by paying 2 and removing a +1/+1 counter from it, creating four 1/1 Spirit creature tokens with flying.
2. Activate Phyrexian Altar three times by sacrificing three Spirits, adding 2.
3. When the Spirits die, Twilight Drover triggers three times, putting three +1/+1 counters on itself.
4. Repeat.

This elegant loop turns Twilight Drover into a self-sustaining engine by utilizing Phyrexian Altar to recycle tokens directly into the mana needed for future activations. While the Drover's ability would normally only break even on mana, the addition of Anointed Procession completely shatters the math by doubling your output at every single step, flooding the board with Spirits and generating an excess of colored mana. As those tokens are continuously sacrificed and leave the battlefield, Twilight Drover grows ever stronger, turning every iteration into a cascade of compounding value.
