Can I use the Blade Dancer ready when chosen ability to ready Irelia in the middle of a showdown assuming I've chosen her with En Garde for example?

Question

Accepted Answer

Yes, you can use the **Blade Dancer** legend ability to ready **Irelia, Fervent** in the middle of a showdown after playing **En Garde** on her.

### How the Interaction Works
Because **En Garde** is a [Reaction], it can be played at any time (including during a showdown). When you play it and choose Irelia, you trigger her ability. Because the Blade Dancer legend ability triggers on "choosing a friendly unit," it will also trigger in response to you choosing Irelia with En Garde.

### Sequence (assuming a standard showdown chain)
1. **Play En Garde:** You play **En Garde** and choose **Irelia, Fervent** as the target.
2. **Triggers added to the chain:**
   *   **Irelia's ability:** "When you choose... me, give me +1 Might" is placed on the chain.
   *   **Blade Dancer's ability:** "When you choose a friendly unit, you may... ready it" is placed on the chain.
3. **Resolution:** The chain resolves in **LIFO (Last-In, First-Out)** order:
   *   **Blade Dancer resolves:** You may pay the cost to ready Irelia.
   *   **Irelia's Trigger (from being readied):** Because she was successfully readied, her ability triggers again, granting her another +1 Might.
   *   **Irelia's Trigger (from being chosen):** The trigger from En Garde's targeting resolves, granting her +1 Might.
   *   **En Garde resolves:** The spell itself resolves, granting her the +1 (or +2 if she is the only unit you control there) Might.

### Key Nuances
*   **Triggering vs. Choosing:** Per **RiftJudge FAQ #220** and **#8590**, while the Blade Dancer legend ability does *not* technically "choose" or "target" Irelia (so it doesn't trigger her "when you choose" ability), the act of readying her successfully triggers her "when you ready me" ability.
*   **Illegal to Ready already Ready:** Per **Rule 415.1.b** and **RiftJudge FAQ #10135**, you cannot ready a unit that is already ready. For this sequence to grant the extra +1 Might, Irelia must be **exhausted** before the Blade Dancer ability resolves.
*   **Reaction Timing:** Because En Garde is a [Reaction], it is legal to play it in a closed state during a showdown. Since the Blade Dancer ability is a triggered ability, it functions normally on the chain.

This interaction is a very effective way to stack multiple Might bonuses on Irelia during a single showdown.
