When playing Sabotage, do you reveal the opponent's hand and choose a card before or after reactions can be played?

Ruling: When you play Sabotage, you choose the opponent when playing it, then reactions can be played. Once Sabotage begins to resolve, you reveal their hand, choose a card, and recycle it all as one action. Countering the spell prevents the reveal from ever occurring.

Sequence:

• Play Sabotage and choose opponent
• Reactions can be played
• Once Sabotage resolves: reveal hand, choose card, and recycle (all in one action)

Nuances:

• You cannot react in the middle of resolution of a card
• Cards in hand are never targets as they are not public information
