Return the Favor copies Twinflame targeting Priest of Urabrask and Eternal Witness; the token Priest adds 3 red mana while the token Witness returns Return the Favor to hand, funding the next iteration. Every loop dumps a haste Priest and Witness token onto the battlefield, fires every ETB and magecraft trigger in the deck, and the original Twinflame hasn't even resolved yet — storm count climbs with each pass through step 2.

Cheaper, tighter, alternate lines

The combo has no cheaper replacement for Return the Favor's copy effect in Gruul — that card is load-bearing. The loop produces infinite red but no green, so lean on red payoffs like Reckless Charge, Grapeshot, or Impact Tremors as the kill rather than anything requiring green mana; Impact Tremors in particular closes from any board state the moment the engine turns on.
