Cabal Therapy

You name the card as Cabal Therapy resolves, not as you cast it. Then the targeted player reveals their hand and discards if appropriate. No player may choose to take actions between you naming the card and the targeted player revealing and discarding.

You must still follow any timing restrictions and permissions, including those based on the card’s type. For instance, you can cast a sorcery using flashback only when you could normally cast a sorcery.

“Flashback [cost]” means “You may cast this card from your graveyard by paying [cost] rather than paying its mana cost” and “If the flashback cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack.”
