Voltaic Construct + Elvish Archdruid + Transmogrifying Licid

Voltaic Construct

Elvish Archdruid

Transmogrifying Licid

How it works

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

This clever loop turns your druidic commander into a one-elf mana battery by transforming the nature of your battlefield. While Elvish Archdruid natively taps for an enormous amount of green mana thanks to its own lord bonus, it isn't an artifact creature on its own—which is where Transmogrifying Licid steps in to permanently graft an artifact type onto it. Once the Archdruid is successfully wearing the Licid, Voltaic Construct can step in with its untap ability, using a sliver of the generated mana to ready the Archdruid for another activation and yielding infinite green mana.
