Basking Broodscale combo wants to chain Ancient Stirrings and Malevolent Rumble into Urza's Saga and Eldrazi Temple ramp toward Devourer of Destiny and Emrakul, so Meltdown at X=1 or X=2 answers Urza's Saga's Construct tokens and any cheap artifacts they commit early. Unholy Heat kills Basking Broodscale (2/2, or larger after Adapt but still low toughness) and Glaring Fleshraker (2/2) cleanly, and with delirium it also handles a Devourer of Destiny at 6 toughness. Tormod's Crypt and Nihil Spellbomb are mostly insurance against Emrakul or reanimation-style value from their graveyard, though this deck is not primarily graveyard-based — prioritize them lower if board space is tight. Keep our clock fast since they are a slower ramp deck that struggles against early pressure.
