What happens when Facebreaker gets played on Vilemaw Lair?

When you play Facebreaker at Vilemaw's Lair, the following occurs:

The Ruling

Facebreaker will successfully resolve, stunning both the targeted friendly unit and the targeted enemy unit. Because Vilemaw's Lair only prevents "moving" units to the base, and stunning or recalling units is not considered a "move" action, the card functions normally.

Sequence of Events

1. Playing Facebreaker: You play Facebreaker targeting a friendly unit and an enemy unit at Vilemaw's Lair.
2. Resolution: The spell resolves, and both units become stunned.
3. Combat Damage: Because the units are stunned, they do not contribute their might to combat damage (Rule 410.1.b).
4. End of Combat (Cleanup): If the combat ends and units from both players are still present at the battlefield, the attacking units will be recalled to their base.
   • Important: Even though Vilemaw's Lair states "Units can't move from here to base," this restriction does not apply to recalls. Recalls are mechanically distinct from moves, so the attacking units will return to base as normal.

According to RiftJudge FAQ #8489:

"In Riftbound, Recall is not a move. Vilemaw's Lair only prevents the 'Move' action. The cleanup step of combat that returns attackers to base is a recall effect, which bypasses the restriction on the card."
