Voltaic Construct + Mycosynth Lattice + Bighorner Rancher

Voltaic Construct

Mycosynth Lattice

Bighorner Rancher

How it works

1. Activate Bighorner Rancher by tapping it, adding at least 3.
2. Activate Voltaic Construct by paying 2, untapping Bighorner Rancher.
3. Repeat

By weaving Mycosynth Lattice into the fabric of the battlefield, every permanent becomes an artifact—meaning Bighorner Rancher is suddenly an artifact creature alongside its natural type. This clever transformation allows Voltaic Construct to target and untap the Rancher for a mere two mana. Because the Rancher's tap ability yields green mana equal to the greatest power among your creatures, you generate more than enough energy to pay the Construct's activation cost and still come out ahead. The result is an infinite loop that floods your mana pool with limitless green mana and leaves your artifact creatures perpetually refreshed and ready for whatever follows.
