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.
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.
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.
