How does Stacked Deck and Nocturne work? Explain how do they enter the chain and resolve. Do a deep analysis.

The interaction between Stacked Deck and Nocturne is a specific sequence where a card's ability triggers during the resolution of another card's effect.

The Interaction Sequence

According to FAQ 6744 and FAQ 1157, the resolution follows this specific order:

1. Stacked Deck is played: You place Stacked Deck on the chain.
2. Stacked Deck resolves: You look at the top 3 cards of your Main Deck.
3. Nocturne triggers: If Nocturne is among the 3 cards, its ability triggers. You may choose to banish it.
4. Nocturne becomes pending: When you choose to banish Nocturne, it is removed from the deck and placed on the chain as a pending item.
5. Finish Stacked Deck: You complete the resolution of Stacked Deck by choosing one of the remaining cards to put into your hand and recycling the others.
6. Finalize Nocturne: After Stacked Deck finishes resolving and is placed in the trash, the chain proceeds to finalize the pending items. You now pay the cost for Nocturne (the [A] cost) and it enters play.

Deep Analysis of Mechanics

• Triggering: Nocturne’s ability triggers because Stacked Deck instructs you to "look at" the top 3 cards. This satisfies the condition for Nocturne to be banished and placed on the chain as a pending item.
• Chain State: When you banish Nocturne, it enters the chain as a pending item. Because it is a unit, it does not use the chain in the same way a spell does; it enters the chain to be finalized.
• Resolution Order: Per Rule 333.1.b, items are finalized in the order they were appended to the chain. Since Stacked Deck was already on the chain and resolving, and Nocturne was added as a pending item during that resolution, Nocturne finalizes after Stacked Deck has fully resolved and moved to the trash.
• Cost Payment: You do not pay for Nocturne when it is banished or when it is placed on the chain as a pending item. You pay the [A] cost during the Finalize step (Rule 333.1), which occurs after Stacked Deck has finished resolving. As noted in FAQ 1157, you can exhaust runes to float energy at this moment to pay for the Nocturne.
• Nocturne's Status: If you reveal multiple Nocturnes, you can banish all of them. They will all become pending items on the chain and you will finalize them one by one after Stacked Deck finishes.

Summary of Key Rules:

• Rule 333.1: Pending items must be finalized before the chain proceeds to the next step.
• Rule 356.2: Once finalized, a unit leaves the chain and becomes a game object on the board.
• FAQ 6744: Confirms that playing Nocturne does not count as your "one card" from Stacked Deck; you still get to pick one of the remaining cards for your hand.

Note: I could not fully verify this ruling against the retrieved rules, specifically regarding FAQ 7941.
