"Warmth. Safety. A fully-stocked larder. You'll find nothing like Edgewall Keep in the wilds, I promise you that!"

Edgewall Innkeeper

Whenever you cast a creature spell that has an Adventure, draw a card. (It doesn't need to have gone on the adventure first.)

The List

Throne of Eldraine

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.

Edgewall Innkeeper's ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.

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.
