Funny, because a poison decks (good ones anyways) are completely built around what they do, and Purify can completely wreck that in one shot for 1

quanta. Now which is overpowered?
Not that I won't mind more counters to Poison. Yet we have Miracle that wrecks a deck's effort for 12

and Holy Light and Heal that do far more manageable amounts for less. Why not extend that?
