Marwyn, the Nurturer taps for at least 7 green; Mobilize untaps all creatures for 1 green, leaving a net surplus. Temur Sabertooth bounces Eternal Witness for 2 green, and Eternal Witness returns Mobilize on entry for another 3 green, closing the loop each cycle. The whole thing lives in Marwyn elf-ball shells that are already stacking +1/+1 counters through Elvish Clancaller or Joraga Warcaller — hitting 7 power is the setup the deck wants anyway.

Cheaper, tighter, alternate lines

Vitalize is a direct substitute for Mobilize — same effect, same cost, same slot. If Temur Sabertooth is removed, Erratic Portal does the same bounce work for 1 colorless. Infinite green mana doesn't close the game alone; pair this with Craterhoof Behemoth as an ETB kill or Walking Ballista as a mana sink.
