This is a damage race where disrupting the opponent's madness engine is the priority — counter a Faithless Looting or Highway Robbery and their entire turn collapses, so all five Pyroblast effects come in as cheap, efficient disruption that doubles as burn to the face. Relic of Progenitus is critical to shut off Lava Dart's flashback, which is their most efficient way to kill your Voldaren Epicures and block your go-wide turns; tap it at end of their turn to exile the graveyard before they can flash it back. Chain Lightning is the weakest burn spell here since the opponent can redirect it back at you for RR, and End the Festivities is a liability when it kills your own Voldaren Epicures and Goblin Bushwhackers. Clockwork Percussionist and excess Experimental Synthesizers are trimmed because this game is decided on speed — you want every card to either deal direct damage or counter a key spell, not spend mana on value that resolves too slowly.
