If Fiora gains Deflect after an opponent has already targeted her with a spell (by increasing her might in reaction), does the opponent need to recycle a card for Deflect?

Ruling: No, the opponent does not need to recycle a card. Once a spell is finalized (costs paid and targets chosen), gaining Deflect afterward does not trigger the Deflect cost requirement.

Sequence:

• Opponent plays spell targeting Fiora (who does not have Deflect yet)
• Opponent pays costs and chooses targets (spell is finalized)
• Player reacts by increasing Fiora's might, giving her Deflect
• Spell resolves without requiring the Deflect cost

Nuances:

• It doesn't matter if Fiora gains Deflect before the spell resolves; what matters is whether she had Deflect when the spell was finalized (when costs were paid and targets were chosen)
