Agatha's Soul Cauldron + Myojin of Towering Might + Tekuthal, Inquiry Dominus + Workhorse

Agatha's Soul Cauldron

Myojin of Towering Might

Tekuthal, Inquiry Dominus

Workhorse

How it works

1. Activate Tekuthal using Myojin of Towering Might's ability by removing an indestructible counter from it, putting six +1/+1 counters on Workhorse, and two +1/+1 counters on any creature you control.
2. Activate Workhorse three times by removing three +1/+1 counters from it, adding CCC.
3. Activate Tekuthal by paying 3 and removing three +1/+1 counters from Workhorse, putting an indestructible counter on it.
4. Repeat.

This fascinating loop transforms Workhorse into an inexhaustible mana engine by leveraging the incredible engine-building power of Agatha's Soul Cauldron. By exiling Myojin of Towering Might into the Cauldron, your creatures gain access to its massive counter-distribution ability, which Tekuthal, Inquiry Dominus then supercharges into a net-positive surge of counters thanks to its doubled proliferation replacement effect. You use Workhorse's native ability to strip away its own counters for mana, while funneling those counters back and forth to fuel Tekuthal's cost-reduction and counter-multiplication requirements. The result is a self-sustaining web of growth that yields infinite mana and arbitrarily large creatures ready to trample the opposition.
