- Claim replacement effects are used after Reactions to winning/losing the challenge, and after gaining the Unopposed bonus, right before Claim is applied. These effects do not resolve immediately, rather they modify the way claim will be applied after all interrupts are played. If multiple claim replacement effects are played (e.g. Seastone Chair, Vengeance for Elia), only the most recently played one applies.
- Dagmer's ability creates a lasting effect that is independent of its sourse, meaning that the location will stay under your control even if Dagmer himself leaves play. Taking control of a card does NOT give you control of its attachments or duplicates. In order to attach a duplicate you need to own and control both the dupe and the card being duped. While you control another player's unique card, that player cannot marshal or put into play another copy of that card.
