Voltaic Construct + Llanowar Tribe + Transmogrifying Licid

Voltaic Construct

Llanowar Tribe

Transmogrifying Licid

How it works

1. Activate Llanowar Tribe by tapping it, adding
2. Activate Voltaic Construct by paying 2, untapping Llanowar Tribe.
3. Repeat

This clever combination turns a humble dork into an engine for infinite green mana by weaving together some unusual type-changing mechanics. You begin by using Transmogrifying Licid to turn Llanowar Tribe into an artifact creature, which is vital because Voltaic Construct can only target artifact creatures with its untap ability. Once the tribe is properly classified as an artifact, tapping it with Llanowar Tribe to produce a surge of green mana leaves you with more than enough resources left over to pay for Voltaic Construct's untapping cost. Looping this process yields infinite green mana and infinite untaps for all your artifact creatures, ready to fuel whatever massive spells you need to close out the game.
