Sultai Ascendancy
The wedge ascendancy that ships a graveyard engine instead of a tempo payoff, and the choice of upkeep timing is the whole design. Several of the clan ascendancies in this cycle reward casting and combat; this one quietly does its work before you draw, sculpting the top of your library and feeding the yard. Surveil 2 every turn is a slow but relentless filter: it digs toward what you want, buries what you do not, and can dump up to two cards into the graveyard per trigger to stock the delve, flashback, and reanimation payoffs that black-green-blue has always wanted to fuel. The cost of that inevitability lands entirely up front: a three-mana enchantment with no immediate impact on the board has to justify a slot against ramp, removal, and threats that touch the board on arrival, and a passive upkeep trigger only matters if you already have enough turns to spend. What it lacks in tempo it pays back in attrition, the sort of engine that wins a long game it does not actually help you reach. Among the Sultai card-advantage pieces it sits closer to a glacial value machine than a combo enabler: a grind-deck commitment that asks you to build around the graveyard it fills rather than to race with it.
