Anafenza, Unyielding Lineage

Endure is the mechanism that recasts this version of the warlord as an aristocrats payoff rather than the graveyard-hate hatebear her original incarnation played as. The choice baked into every death trigger (two counters onto the body, or a 2/2 Spirit token) is what gives the card its flexibility: pile the counters when you want a threat that ends games through first strike, or bank the tokens when you need bodies to keep the sacrifice loop fed. Flash is the load-bearing keyword. A 2/2 for three that must be deployed on your own turn is trivially answered before it accrues value; flashing her in at the end of an opponent's turn, before your own creatures start dying, means the first death trigger she sees can happen before anyone gets a clean window to remove her. The nontoken restriction is the discipline that keeps the engine from spiraling on its own output: you cannot sacrifice a Spirit she made to make another Spirit, so each trigger has to be paid for with a real creature. What she rewards is a board that was going to trade and die anyway, converting attrition you were already spending into a growing white army. It is the structural work white weenie has always wanted from its death triggers, folded into a single legendary body that can ambush and block above its weight.
