Abzan Ascendancy

The clan ascendancies were built as wedge-color payoffs, and this one reads its three colors precisely: the entry trigger is the green-white go-wide reward (a board-wide pump that swings combat math the moment it resolves), while the death trigger is the black-white attrition engine that turns your own losses into recurring fliers. The interplay is the whole design. The +1/+1 counters make your board harder to clear at the point you most want a wall held; and once the removal starts coming, every nontoken creature that dies leaves a 1/1 flier behind, so a sweeper that should reset the table instead reloads it with evasive bodies. That nontoken clause is the discipline keeping it from spiraling: the Spirits it makes cannot themselves feed the engine, so it rewards a board of real creatures rather than a token loop. It punishes the two things midrange decks lean on to stabilize, the alpha-strike block and the board wipe, and asks the opponent to find removal that exiles or that strands the body somewhere death cannot trigger. Both abilities fire and then step back: there is no mana sink, no upkeep tax, nothing to activate turn after turn. Once it resolves, it simply changes the value of every trade made around it, a subtler win condition than the splashy ramp-and-counter ascendancies in the same cycle ever managed.
