Ashaya, Soul of the Wild + Scryb Ranger + Rofellos, Llanowar Emissary

Ashaya, Soul of the Wild

Scryb Ranger

Rofellos, Llanowar Emissary

How it works

1. Activate Rofellos by tapping it, adding at least .
2. Activate Scryb Ranger by returning it from the battlefield to your hand, untapping Rofellos.
3. Cast Scryb Ranger by paying 1.
4. Repeat.

This ingenious loop transforms your entire creature base into a wellspring of infinite green mana through Ashaya, Soul of the Wild, which passively reclassifies all your nontoken creatures as Forest lands in addition to their other types. With that crucial land type applied, Rofellos, Llanowar Emissary taps to produce an avalanche of green mana scaled directly to your creature-count. You then use Scryb Ranger's ability—bouncing a "Forest" back to your hand to untap Rofellos—to reset the Elf for another activation. Because Ashaya turns Scryb Ranger into a Forest right back on the battlefield, you can simply recast it for `{1}{G}` using a fraction of the generated mana and repeat the process indefinitely.
