Emerge (You may cast this spell by sacrificing a creature and paying the emerge cost reduced by that creature's mana value.)
When you cast this spell, you may exile your hand. If you do, draw three cards.
Flying
Each creature spell you cast has emerge. The emerge cost is equal to its mana cost.
Drop Herigast (often via Emerge, sacrificing a token or mana dork while dumping and refilling your hand for three cards), then cast all your creatures by sacrificing other creatures to slash their cost. You churn through fatties and value creatures while triggering ETB and death effects, building an overwhelming board or assembling a sacrifice-fueled combo. Close the game with huge attackers or a fling-style burst.
Massive cost reduction lets mono-red cheat out giant creatures and Eldrazi titans turns ahead of schedule
Built-in card advantage from the cast trigger keeps a notoriously card-starved color refueled
Synergizes with ETB and death triggers, since every creature you sac and recast doubles as fuel
Flying 7/7 body that pressures life totals and finishes games on its own
Requires creatures on the battlefield to fuel Emerge, so an empty board leaves you stuck
Commander tax and a 9 mana value make recasting after removal punishing
Mono-red lacks interaction, spot removal protection, and meaningful recursion
Highly creature-dependent, so wraths and graveyard hate hit very hard
Slow if you don't curve into early sacrifice fodder
Doubles the ETB damage from every emerged creature, helping convert board presence into direct kills.
Lean into reliable, recurring fodder—Token producers and creatures that return themselves like Squee or Reassembling Skeleton—so Emerge is always online. Add fast mana (Sol Ring, Jeska's Will, Mana Geyser) and impactful colorless bombs to cheat out faster, plus a couple of free sacrifice outlets to protect threats and enable combo flings. Tighten the curve with cheap dorks and tutors like Sneak Attack effects, and add graveyard recursion to grind through inevitable board wipes.
