Robber of the Rich

If you cast an Adventure with Robber of the Rich, it's you, not the card's owner, who may cast the creature later.

If Robber of the Rich leaves the battlefield, the effect allowing you to cast the exiled card if you attacked with a Rogue continues to apply, even during later turns—as long as you attack with a Rogue during those later turns.

Robber of the Rich's effect doesn't change when you can cast the exiled card. For example, if you exile a sorcery card, you can cast it only during your main phase when the stack is empty.

An effect that instructs you to “cast” a card doesn't allow you to play lands.

Casting an exiled card causes it to leave exile. You can't cast it multiple times.

If a creature is attacking a planeswalker, the controller of the planeswalker is the defending player.
