Jace, the Mind Sculptor I dont know what it is about Jace, the Mind Sculptor, but something about the incredible power level of this card paired with its long-term seat on the banlist make it such an ominous and powerful card

Ideal hideaway targets include Rise of the Dark Realms, Revel in Riches, Sorin Markov, or In Garruk's Wake (if you're in a pinch), among many others
