Vantress Transmuter // Croaking Curse

Hexproof and shroud won’t prevent a Role from becoming attached to a permanent if the ability creating that Role attached to that permanent doesn’t target it.

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.

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.
