If a Thrill of the Hunt choosing Brynhildr is played as a reaction to Dazzling Aurora trigger, what happens?

Question

Accepted Answer

### Interaction Analysis: Dazzling Aurora and Thrill of the Hunt

When **Dazzling Aurora** triggers at the end of the turn, it creates an effect on the chain. You may respond by playing **Thrill of the Hunt** to banish and play Brynhir Thundersong to a battlefield.

### The Sequence of Events
1.  **Dazzling Aurora Triggers:** The ability is placed on the chain.
2.  **Playing *Thrill of the Hunt*:** You play the spell in response to the Dazzling Aurora trigger.
3.  **Chain Resolution (LIFO):**
    *   **Resolution of *Thrill of the Hunt*:** Brynhir Thundersong is banished and played to a battlefield.
    *   **Brynhir’s Trigger:** Brynhir’s "When you play me" ability is placed on the chain above the Dazzling Aurora trigger.
    *   **Resolution of Brynhir’s Trigger:** Once this resolves, opponents are prevented from playing cards from their hand for the remainder of the turn.
    *   **Resolution of Dazzling Aurora:** The Dazzling Aurora ability resolves. If this ability requires your opponent to play a unit they reveal, they will be unable to do so because of the restriction imposed by Brynhir’s resolved ability (as playing a unit via a card's effect counts as playing a card).

### Key Rulings & Nuances
*   **Brynhir’s Timing:** Per **RiftJudge FAQ #2534** and **#638**, Brynhir's "When you play me" ability is a triggered ability that goes on the chain. Players may react to it before it resolves. Once it resolves, opponents are shut off from playing cards for the rest of the turn.
*   **Restriction on Playing Cards:** Per **FAQ #5853** and **#9614**, Brynhir’s effect prevents opponents from playing cards, including playing units via a card's effect like Dazzling Aurora. 
*   **Order of Operations:** Dazzling Aurora’s effect executes after Brynhir has entered the board and her ability has resolved.
*   **Battlefield Control:** According to **Rule 187.4.c**, the cleanup phase is suspended while there are items on the chain, ensuring you remain in control of your battlefields throughout this process.
