This spell costs 
less to cast for each creature on the battlefield.
Blasphemous Act deals 13 damage to each creature.
Why is this card good?
Blasphemous Act is arguably the best red board wipe in Commander, and its ubiquity (top-25 card) is earned. In a typical four-player game, the battlefield is clogged with creatures, so this routinely costs just or . 13 damage means almost nothing survives — it kills indestructible-via-toughness creatures and most big threats outright.
Play it in basically any deck with red that wants a wrath. It's especially good in:
- Control / Spellslinger decks needing a cheap reset.
- Aristocrats decks — pair it with payoffs like Mayhem Devil or Zulaport Cutthroat for a one-card finisher.
- Punisher / damage-doublers (Torbran turns this into a player-killing nuke too).
When NOT to play it: dedicated token swarm or go-wide aggro decks where you're the one with the most creatures — you'll just blow up your own board. Also skip it if your creatures lean on high-toughness bodies that can survive normal wipes; 13 damage doesn't care.
A near-auto-include sweeper for most red midrange/control lists.
