: Untap Fain.
Fain turns counters, creatures, and artifacts into one another, letting you fuel sacrifice payoffs, ramp via Treasure, and grow threats on demand. You build a value engine that loops fodder into counters, counters into Treasure, and Treasure into Inklings, then untap Fain with to do it all twice in a turn. You grind the table out with relentless incremental advantage and convert it into a big swing or a sacrifice/aristocrats finish.
Extremely flexible engine that bridges +1/+1 counters, artifacts, and Treasure ramp
Untap ability means his abilities aren't once-per-turn — huge with mana
Mono-black gives deep access to tutors, recursion, and reanimation
Generates value from spare counters and tokens that would otherwise sit idle
Each ability is slow and incremental without an untapper or mass token production
Heavily reliant on Fain himself, so commander removal and tax stunt the deck
Vulnerable to graveyard hate when leaning on recursion/aristocrats
Can fold to fast combo decks since the engine takes time to assemble
