This clever loop starts by using Tezzeret, Betrayer of Flesh's minus ability to turn White Lotus Tile into a 4/4 artifact creature, making it a legal target for both its own mana-producing potential and subsequent untapping. Once animated, White Lotus Tile taps for at least three mana, easily fueling the process. This is where Tezzeret, Betrayer of Flesh's static cost-reduction ability shines, shrinking the activation cost of Voltaic Construct's untap ability down to just a single generic mana. With the mana generated far exceeding the cost to untap, Voltaic Construct can repeatedly refresh White Lotus Tile to harvest boundless colored mana.
