Ashaya, Soul of the Wild + Market Festival + Farmstead Gleaner

Ashaya, Soul of the Wild

Market Festival

Farmstead Gleaner

How it works

1. Activate Farmstead Gleaner by tapping it, adding .
2. Market Festival triggers, adding two mana of any color(s).
3. Activate Farmstead Gleaner by paying 2 and untapping it, putting a +1/+1 counter on it.
4. Repeat

The magic of this loop lies in Ashaya, Soul of the Wild, whose static ability turns every nontoken creature you control into a Forest land in addition to its other types. Because Farmstead Gleaner is now a Forest, you can tap it directly for green mana, which is drastically amplified by Market Festival enchanting it to produce an extra two mana of any color whenever it taps. You then use a portion of that generated mana to pay the activation cost of Farmstead Gleaner's untap ability, placing a +1/+1 counter on it in the process and leaving you with a net surplus of mana to repeat the cycle indefinitely.
