Betor, Ancestor's Voice runs an Abzan engine that turns both sides of the life total into value. At each end step, life gained that turn becomes +1/+1 counters on one other creature, and life lost that turn sets the mana value of a creature card it can return from the graveyard to the battlefield. The deck builds on lifelink, drain and incidental lifegain to grow threats, pays life on purpose through self-damage and life-payment effects to raise the reanimation ceiling, and keeps the graveyard stocked so every turn ends with a bigger creature and a free body back. How it wins: It closes games by draining opponents through lifegain payoffs that turn each life gained into opponent life loss, backed by large counter-laden fliers and lifelinkers attacking. Key roles: - Lifegain sources: Repeatable and incidental life gain, from lifelink creatures, soul-sister-style triggers and drain spells, so Betor, Ancestor's Voice has a large number to convert into +1/+1 counters every end step. (Betor, Ancestor's Voice) - Self-damage and life payment: Cards that pay life, deal damage to their controller or cost life as a resource, which raise the life-lost count so the end-step reanimation can reach bigger creatures. These also fuel card draw. - Counter payoffs and amplifiers: Effects that double or add extra +1/+1 counters, and creatures that gain abilities or trigger off counters, so each end-step placement scales into a dominant threat. - Graveyard setup and reanimation targets: Self-mill, discard and sacrifice outlets that put strong creatures in the graveyard, plus high-impact creatures worth returning, so the life-loss reanimation always has a good target. - Drain finishers: Payoffs that make opponents lose life whenever life is gained, or turn a large life total and counters into damage, ending games once the gain-and-drain loop is running.
