At the beginning of your end step, if you descended this turn, each opponent may discard a card or sacrifice a permanent of their choice. Zoyowa deals 3 damage to each opponent who didn't. (You descended if a permanent card was put into your graveyard from anywhere.)
Zoyowa is a cheap, recursive aggro-attrition engine: every turn you put a permanent card into your graveyard (descend) to force each opponent to discard, sacrifice, or take 3. You set up sacrifice fodder, fetchlands, and self-mill enablers to trigger descend reliably, then grind everyone's hands and board down while chipping life totals. Deathtouch lets her trade up in combat and discourages attacks while you assemble bigger payoffs.
Extremely cheap (2 MV) and easy to recast, so the engine comes online turn 2-3
Hits all opponents every end step, taxing them no matter what choice they make
Punishes go-wide and big-permanent strategies through forced sacrifice
Synergizes naturally with sacrifice, fetchlands, and graveyard-matters shells already strong in Rakdos
Deathtouch makes her a reliable blocker and combat threat
Opponents choose how to respond, so it's slow incremental pressure rather than burst
Needs consistent descend enablers or the trigger fizzles entirely
Low toughness and creature-removal magnet as a known engine
Three-damage pings are easily offset by lifegain at higher tables
Lacks card advantage of its own beyond the political pressure
Generates treasures you can sacrifice to descend and ramp into bigger threats.
Add more free or cost-effective descend enablers—fetchlands, treasure makers, and cheap sacrifice outlets like Viscera Seer and Goblin Bombardment—so the trigger never misses. Layer in damage multipliers (Mayhem Devil, Blood Artist, Zulaport Cutthroat) and recursion (Feldon, Bolas's Citadel, Reanimate) to convert the chip damage into a real clock. Top-end upgrades include fast mana (Mana Crypt, Jeweled Lotus) and a compact combo like Mayhem Devil plus a sacrifice loop to end games outright.
