Paradox is an ability word from Doctor Who that rewards casting spells from anywhere other than your hand. This includes spells cast from exile, graveyards, libraries, and other unusual locations.
Suspend, flashback, rebound, foretell, cascade, and impulse draw can all trigger paradox abilities. The Twelfth Doctor and The Thirteenth Doctor provide commanders capable of turning that collection of temporal oddities into a cohesive deck.
