How does Blind Fury work? Do you reveal and play the opponent's card, and who controls it?

Ruling: You reveal cards from your opponent's deck, choose one, banish it, then play that card from banishment. You become the Controller of any unit played this way, while your opponent remains its Owner.

Sequence:

• Reveal cards from opponent's deck
• Choose one card
• Banish the chosen card
• Play the chosen card from banishment (on the same chain, as a pending item)
• If the card cannot be played for any reason, it stays banished

Nuances:

• The banishment step was added via errata as a fail-safe in case the chosen card cannot be played
• Units are played immediately as you cannot respond to units being played
• If you choose a spell with no legal targets, it stays banished
• Controller vs Owner distinction matters for card effects that reference those terms
• The card is played on the same chain (not a new chain) as pending items are added before chain end
