Other creatures you control have haste.
Whenever one or more face-down creatures you control deal combat damage to a player, draw a card.
Whenever a face-down creature you control dies, return it to the battlefield face down under its owner's control if it's a permanent card, then turn it face up.
Yarus turns face-down creatures (morph, megamorph, manifest, disguise) into a relentless aggro-value engine: every hasty face-down attacker draws you cards, and dead ones recur themselves to be flipped again. You flood the board with cheap 2/2s, swing immediately thanks to global haste, draw off connecting damage, and grind out value by sacrificing and reflipping morphs in a near-inexhaustible loop.
Add efficient sacrifice outlets (Viscera Seer, Goblin Bombardment) and reanimation-loop payoffs to abuse the death trigger, plus manifest enablers like Lurking Predators to cheat huge creatures into face-down status. Improve mana with Gruul ramp (Cultivate, fast dorks) and top-end finishers such as Craterhoof Behemoth or Pathbreaker Ibex to convert your wide hasty board into one-shot kills. Round out with protection (Heroic Intervention) and a couple of reusable bounce/blink effects to reset and recur your best morphs.
