Can you fight or flight at Vilemaw's Lair?

Question

Accepted Answer

No, you cannot use **Fight or Flight** to move a unit from **Vilemaw's Lair** to your base.

While you are legally allowed to activate or play **Fight or Flight** targeting a unit in **Vilemaw's Lair**, the movement effect will fail to resolve.

### Why this happens:
*   **"Can't" overrides "Can":** **Vilemaw's Lair** explicitly states, "Units can't move from here to base." In *Riftbound*, a "can't" restriction always overrides a "can" effect.
*   **Valid Activation:** You can still legally play the card (for example, to trigger an "on spell cast" ability like Ember Monk), but the unit will remain in the Lair because the movement is blocked by the battlefield's effect.
*   **Recall vs. Move:** Note that "Recall" effects (such as those from Zhonya's Hourglass or end-of-combat cleanup) are not considered "movement" and are therefore not blocked by **Vilemaw's Lair**.

This ruling is consistent with **RiftJudge FAQ #8471**, which confirms that while the activation is valid, the movement effect fails to resolve.
