Can Blind Fury be played during a showdown as a defender, and does it allow you to take your opponent's revealed card and play it on your side of the battlefield?

Ruling: Blind Fury can be played during a showdown if you have focus, but it reveals and plays a card from the top of the main deck, not from hidden cards at the showdown battlefield. In a 1v1 game, your opponent reveals the top card of their deck and you play it to your side of the battlefield.

Sequence:

• Play Blind Fury (requires focus)
• Opponent reveals the top card of their deck
• You play that revealed card to your side of the battlefield

Nuances:

• In multiplayer games, you choose which opponent's deck to reveal from and play the card
• The card comes from the main deck, not from hidden showdown cards
• You play the opponent's card to your own board, not force them to play it on theirs
