Here are some cards similar to “Singularity Rupture” (2R, Sorcery, deals with sacrificing artifacts/enchantments for damage) in red:
1. “Shrapnel Blast”
Sacrifice an artifact: Deal 5 damage to any target.
Reason: Also requires an artifact sacrifice for direct damage.
2. “Barrage Ogre”
Tap, sacrifice an artifact: Deal 2 damage to any target.
Reason: Red, artifact-sacrifice for burn, though repeatable.
3. “Goblin Bombardment”
Sacrifice a creature: Deal 1 damage to any target (enchantment, not artifact).
Reason: Sacrifice for damage, but with creatures.
None are strictly identical, but these closely match the theme and color.
