Does Forge Fire Cape work on Ruin Runner?

Question

Accepted Answer

Yes, **Forgefire Cape** works on **Ruin Runner**.

Here is the breakdown of why this interaction works:

*   **Equipping is not targeting:** The **Equip** keyword (and the action of attaching an equipment) does not require you to "choose" or "target" a unit in a way that violates protection abilities. You are simply attaching the gear to a unit you control.
*   **Ruin Runner's protection:** **Ruin Runner** has the ability: *"I can't be chosen by enemy spells and abilities."* This protection only prevents your opponent from targeting it with their spells or abilities. It does not prevent you from targeting or attaching your own equipment to your own **Ruin Runner**.
*   **Effect resolution:** Once **Forgefire Cape** is attached, its effect ("When I attack or defend, deal 2 to all enemy units here") is a triggered ability of the gear. Because this effect does not target (it deals damage to all enemy units at that location), it will function normally even if the **Ruin Runner** is the unit carrying it.
