How does Dazzling Aurora work with Deadbloom Predator Showdown?

When Dazzling Aurora triggers at the end of your turn, it interacts with Deadbloom Predator as follows:

How the Interaction Works

1. Dazzling Aurora Trigger: At the end of your turn, Dazzling Aurora triggers. You reveal cards from the top of your Main Deck until you reveal a unit. You play that unit and recycle the rest of the revealed cards.
2. Playing Deadbloom Predator: If the unit revealed is Deadbloom Predator, its ability allows you to play it directly onto an occupied enemy battlefield.
3. Initiating a Showdown: Because Deadbloom Predator enters an occupied battlefield, it initiates a showdown.

Timing and Sequence

According to the established rulings (FAQ #1207, #4139, #8080), the showdown does not begin immediately. The game must reach a "neutral open state" (where the chain is empty) before the showdown can start.

Sequence:

1. Dazzling Aurora resolves: You reveal cards, find Deadbloom Predator, and play it to an occupied enemy battlefield.
2. Chain Check: If there are any other pending items on the chain (such as a second Dazzling Aurora trigger or "When you play" abilities from the unit), they must resolve first.
3. Cleanup: Once the chain is completely empty, the game performs a cleanup (Rule 322).
4. Showdown Initiation: If the battlefield is still occupied by opposing units, the showdown initiates during the ending step.

Key Nuances

• No "Until you hit Deadbloom": Dazzling Aurora does not specifically search for Deadbloom Predator. It reveals cards until it hits any unit. If that unit happens to be Deadbloom Predator, you gain the option to place it on an occupied enemy battlefield.
• Chain Priority: You cannot start a showdown while the chain is active. If you have multiple Dazzling Auroras, you must resolve all of them and any resulting triggers before the showdown begins.
• End of Turn: The showdown occurs during your end step. After the showdown resolves, the turn passes to your opponent.
