Does Stupefy or Frigid Touch trigger Immortal Phoenix effect to play it from trash?

Question

Accepted Answer

No, neither **Stupefy** nor **Frigid Touch** will trigger the ability of **Immortal Phoenix** to be played from your trash.

According to **RiftJudge FAQ #2625**, Immortal Phoenix only triggers when a unit is killed by a **spell** (either via a "Kill" instruction or via damage dealt by a spell). Stat reduction effects (reducing Might) do not count as "killing a unit with a spell," even if that reduction eventually causes the unit to die due to the game rules during a cleanup phase.

### Why they don't trigger Immortal Phoenix:
*   **Effect Type:** Both *Stupefy* and *Frigid Touch* are stat-reduction spells. They reduce Might rather than dealing damage or issuing a "Kill" instruction.
*   **System Rules:** Units are only "killed by a spell" for the purpose of Immortal Phoenix if the spell has a specific "Kill" action or deals damage that causes the unit to die in the immediately following cleanup (see Rule 428.5.c and FAQ #2625).
*   **Result of Reduction:** As clarified in **RiftJudge FAQ #8663** and **#80**, reducing a unit's Might (even to 0 or below) does not constitute a "kill" by the spell. The death is a consequence of system rules checking Might vs. damage during cleanup, not an action attributed to the spell's effect.

This interpretation is supported by **RiftJudge FAQ #2625**, which explicitly states that Immortal Phoenix cannot be played from the trash when a unit is destroyed by stat reduction effects.
