Does Stellacorn Herder draw a card when it is on a battlefield with attached Guardian Angel and it receives deadly damage that activates Guardian Angel's effect? Stellacorn is transferred to the base after Guardian Angel activation, but does it count as a move?
No, Stellacorn Herder does not draw a card in this scenario.
According to RiftJudge FAQ #2801, the activation of Guardian Angel does not count as a move for the purposes of abilities that trigger "when I move."
Reasoning:
- Recall vs. Move: In Riftbound, "Recall" and "Move" are distinct game actions. Guardian Angel's effect specifically instructs you to "recall" the unit to your base. Because the effect uses the term "recall" rather than "move," it does not satisfy the trigger condition for Stellacorn Herder's ability ("When I move, draw 1").
- Replacement Effect: As established in RiftJudge FAQ #9367 and #9378, Guardian Angel acts as a replacement effect. It replaces the "death" event with a sequence that includes healing, exhausting, and recalling the unit. Since the unit is recalled rather than moved, the "When I move" trigger condition is never met.
This is my interpretation based on the distinction between game actions defined in the rules and clarified in the FAQs. No official FAQ exists for this specific interaction, but it is consistent with the established ruling that recall effects do not trigger move-based abilities.
