When Blind Fury reveals Nocturne, Horrifying from an opponent's deck, how does the interaction resolve? Can the opponent banish Nocturne with its own ability to prevent the Blind Fury player from playing it?

Ruling: When Nocturne is revealed by Blind Fury, the opponent may choose to activate Nocturne's ability to banish it and optionally play it for A power. If they do, Nocturne is no longer available for the Blind Fury player to select and play. If the opponent chooses not to activate Nocturne's ability, the Blind Fury player can select and play it for free.

Sequence:

• Blind Fury begins resolving and reveals Nocturne from opponent's deck
• Nocturne's owner may immediately activate its ability (not a triggered effect) to banish it
• If banished, owner may pay A power to play Nocturne (goes on chain as pending)
• Blind Fury continues resolving with remaining revealed cards
• After Blind Fury resolves, any pending units (like Nocturne) are added to chain and resolve immediately
• In multiplayer, if multiple units become pending, they resolve in the order they became pending (Nocturne would be first)

Nuances:

• Nocturne's ability is optional ("may"), so the opponent can choose not to activate it
• Nocturne's effect is not a triggered ability, so it can be activated immediately during Blind Fury's resolution without waiting
• The opponent can choose to just banish Nocturne without paying to play it, denying the Blind Fury player access to it
• Units being played cannot be responded to and resolve immediately
