Tam makes planeswalkers cheaper and, with all five colors, taps to proliferate once per planeswalker type among the walkers you control. The deck fills the board with planeswalkers, then grows their loyalty by proliferating, and it also makes Jace tokens through the empower enchantments. Cost reducers, loyalty-ability enablers and extra proliferate triggers keep the walkers active every turn. How it wins: Planeswalkers accumulate loyalty from repeated proliferating and drive their ultimates, emblems, repeatable damage and extra turns until opponents are overwhelmed or eliminated. Key cards: - Cost reduction and fixing: Oath of Ajani and Oath of Nissa make planeswalker spells cheaper and easier to cast in any color, so several land per turn. - Proliferate engines: Tekuthal, Inquiry Dominus doubles every proliferate, and Flux Channeler adds one more each time you cast a noncreature spell. - Loyalty ability multipliers: Oath of Teferi and The Chain Veil let each planeswalker activate its abilities more than once per turn. - Ultimate and extra-turn enablers: Ichormoon Gauntlet gives every planeswalker a 0 proliferate and a -12 extra turn, while Lae'zel, Vlaakith's Champion adds extra counters. - Planeswalker payoffs: Chandra, Legacy of Fire and Commodore Guff deal damage that scales with the number of planeswalkers you control, finishing games without combat.
