Equivalent cards to “Starstorm” (red, instant, scalable damage to creatures):
- “Blasphemous Act” (red, cheaper with more creatures, sorcery)
- “Mizzium Mortars” (red, instant for single, overload for all)
- “Comet Storm” (red, instant, scalable but targets creatures/players)
- “Rolling Earthquake” (red, sorcery, scalable, also hits players and walkers)
- “Fault Line” (red, instant, each creature without flying and each player)
Reason: All these are scalable red sweepers or close functional equivalents to “Starstorm.”
