Can you use Pyke's Legend ability in Showdowns?

Question

Accepted Answer

No, you cannot use the legend ability of **Pyke (Bloodharbor Ripper)** during a showdown.

### Ruling
Activated abilities can only be activated during your turn when the game state is Open (the chain is empty), unless they possess the **[Action]** or **[Reaction]** keyword. Because the legend ability of Pyke lacks these keywords, it is not legally timed for use during a showdown, regardless of whether you are attacking or defending.

### Reasoning
*   **Ability Timing:** According to the rules for activated abilities, they must have a speed keyword—**[Action]** or **[Reaction]**—to be used during a showdown (Rule 347, Rule 813).
*   **Showdown State:** During a showdown, players are restricted to playing spells or activating abilities that are legally timed for that state. As documented in numerous precedents (e.g., RiftJudge FAQs #8584 and #9120 regarding Jax, and #2659 regarding Viktor), legend abilities without these specific keywords cannot be activated mid-showdown. 
*   **Pyke's Ability:** The ability "[1], [T] : Return a friendly unit..." does not contain the **[Action]** or **[Reaction]** keyword. Consequently, it is subject to the general restriction that prevents its use during a showdown.
