This loop relies on exploiting the mana-producing potential of Pyramid of the Pantheon once it has accumulated its three brick counters, tapping it for three mana to comfortably fund the sequence. You then use Manifold Key to untap the Pyramid, and Drafna, Founder of Lat-Nam swoops in to bounce Manifold Key back to your hand for cheap. Because Manifold Key costs zero mana to cast, you can redeploy it immediately to repeat the process, while Temur Battlecrier stands by as a helpful enabler for cost reductions elsewhere in your strategy.
