Archaic's Agony - Secrets of Strixhaven (Uncommon) [SOS-107]

Archaic's Agony is a sorcery from Secrets of Strixhaven that deals damage to a target creature based on the number of different colours of mana spent to cast it. This means it can scale up effectively in multi-colour decks while also allowing you to exile cards from your library equal to any excess damage, giving you extra options to play on your next turn. It works well in decks that can generate multiple colours of mana, especially in strategies that focus on creature removal and card advantage.
