Murderous Rider // Swift End

If an adventurer card ends up in exile for any other reason than by exiling itself while resolving, it won't give you permission to play it with its primary characteristics.

If an effect refers to a card, spell, or permanent that has an Adventure, it won't find an instant or sorcery spell on the stack that's been cast as an Adventure.

If you cast an adventurer card as an Adventure, use only its alternative characteristics to determine whether it's legal to cast that spell. For example, if you control Traveling Chocobo ("You may play lands and cast Bird spells from the top of your library.") and Jidoor, Aristocratic Capital is on top of your library, you can play Jidoor, Aristocratic Capital, but you can't cast Overture.
