This delightful engine hinges on Harabaz Druid's ability to scale its mana production with the number of Allies you control, yielding at least five mana to comfortably feed the machinery. With that surplus in hand, Staff of Domination steps in as the ultimate multi-tool: its third ability untaps the Druid for a modest three-mana investment, while its first ability untaps itself for just one mana. By looping these activations, you cleanly generate infinite colored mana, leaving plenty of headroom to leverage the Staff's remaining abilities for infinite card draw, lifegain, and creature untapping.
