This clever loop turns your battlefield into a self-sustaining mana factory by taking full advantage of type-changing magic. First, *The Flesh Is Weak* transforms all your creatures with +1/+1 counters into artifacts, which is crucial because it simultaneously hands *Voltaic Construct* a valid target among your green-aligned forces. Once that foundation is set, *Elvish Archdruid* taps to generate a massive surge of green mana thanks to the other Elves you control—enough to effortlessly feed the {2} activation cost required for *Voltaic Construct* to untap the druid in return. Repeating this process yields infinite green mana and infinite untaps for all your artifact creatures, providing a crushing amount of resources to fuel the rest of your game plan.
