The Commander

At the beginning of combat on your turn, create X tokens that are copies of another target creature you control, where X is one plus the number of instant and sorcery spells you've cast this turn. They gain haste. Exile them at the beginning of the next end step.

Guide

Gameplan

Cast cheap instants and sorceries before combat to pump Rionya's trigger, then copy a high-impact creature (with a big ETB or attack trigger) to flood the board with hasty temporary copies that swing for lethal or chain massive value. You ramp into spell-heavy turns and convert a single combat step into an explosive burst.

Strengths

Generates massive amounts of value/damage in a single combat with the right creature copied
Synergizes with both spellslinger and ETB-payoff strategies
Can produce lethal swings out of nowhere when copying evasive or pinging creatures
Mono-red gives access to fast ritual mana and efficient card advantage like Wheel effects

Weaknesses

Tokens are exiled at end step, so each turn's board must be rebuilt
Heavily reliant on Rionya surviving until combat and on having a good copy target
Vulnerable to board wipes, spot removal on the copy target, and combat hate
Mono-red struggles with sustained card draw, interaction, and recovering from sweepers

Key Cards

Combat Celebrant — Copying it grants extra combat steps, letting you re-trigger Rionya and swing repeatedly for huge damage.
Krenko, Mob Boss — Each copy taps to make Goblins equal to your creature count, snowballing into hundreds of tokens and lethal attacks.
Terror of the Peaks — Every copy entering deals damage equal to its power, turning Rionya's tokens into a direct burn wincon.
Hellkite Tyrant — Hasty copies steal all artifacts on hit or trigger the alternate win, and connecting with several copies wins fast.
Underworld Breach — Recasting cheap spells from the graveyard fuels Rionya's X count and enables explosive combo turns.
Jeska's Will — Refills your hand and dumps a pile of red mana, both fueling extra spells and ramp before combat.

Upgrade Path

Add fast mana (Mana Crypt, Jeweled Lotus, ritual effects) and protection like Deflecting Swat to ensure Rionya connects, plus more efficient cantrips to inflate the X count cheaply. Lean into a dedicated combo finisher—Combat Celebrant loops or Krenko with sac outlets—and include Wheel effects (Wheel of Fortune, Reforge the Soul) to refuel. Prioritize a stronger creature suite where copying just one card ends the game.
