Hildibrand Manderville // Gentleman's Rise

You must follow the normal timing permissions and restrictions for Gentleman's Rise when casting it with the permission of Hildibrand Manderville's triggered ability. You must pay its mana cost (or, if another effect allows, an alternative cost).

If an effect copies an Adventure spell, that copy is exiled as it resolves. It ceases to exist as a state-based action; it's not possible to play the copy as a permanent.

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.

When playing a card as an Adventure, use the alternative characteristics and ignore all of the card's normal characteristics. The resulting spell's color, mana cost, mana value, and so on are determined by only those alternative characteristics. If the spell leaves the stack, it immediately resumes using its normal characteristics.

An effect may refer to a card, spell, or permanent that "has an Adventure." This refers to a card, spell, or permanent that has an adventurer card's set of alternative characteristics, even if they're not being used and even if that card was never cast as an Adventure.

If an effect instructs you to choose a card name, you may choose the alternative Adventure name. Consider only the alternative characteristics to determine whether that is an appropriate name to choose.

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 a spell is cast as an Adventure, its controller exiles it instead of putting it into its owner's graveyard as it resolves. For as long as it remains exiled, that player may play it using its primary characteristics. If an Adventure spell leaves the stack in any way other than resolving (most likely by being countered or by failing to resolve because its targets have all become illegal), that card won't be exiled and the spell's controller won't be able to play that card from exile later.

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.

If an object becomes a copy of an object that has an Adventure, the copy also has an Adventure. If it changes zones, it will either cease to exist (if it's a token) or cease to be a copy (if it's a nontoken permanent), and so you won't be able to cast it as an Adventure.
