Twinflame copies Priest of Urabrask and Eternal Witness via Reverberate; the Priest token produces three red on entry, and Eternal Witness returns Reverberate to hand the moment it resolves, funding the next iteration. The loop asks for five mana to start — three red and two for Reverberate — which is attainable by turn four in a dedicated Gruul storm or magecraft shell like Veyran, Voice of Duality or Zada, Hedron Grinder.

Cheaper, tighter, alternate lines

Heat Shimmer slots in for Twinflame if only one creature target is available, though the steps need adjustment since it targets a single creature. The loop produces infinite tokens and mana but no built-in kill — pair it with Purphoros, God of the Forge or Goblin Bombardment to convert the haste tokens into lethal damage on the same turn stack.
