Can you tap mana runes in the middle of resolving Stacked Deck (e.g., to float mana before recycling when you see cards you want to play)?

Ruling: You cannot tap mana runes in the middle of resolving Stacked Deck. You pay for cards (like Nocturne) while finalizing after Stacked Deck is fully resolved.

Sequence:

• Stacked Deck resolves completely
• You finalize and pay for any cards you want to play (like Nocturne)
• During finalization, you can tap mana runes, float mana, and recycle

Nuances:

• You technically need to tap mana in reaction to something, not in the middle of an ability resolving
• When paying for a card like Nocturne after Stacked Deck, you can tap runes, float mana, then recycle before playing the card
