If Janna is played into a showdown and the opponent reacts with Hidden Fight or Flight to move her to base, does her 'When you play me' ability still heal units?

Ruling: Janna's ability will still trigger and resolve, but it will have no effect if she is moved before it resolves. Since her ability heals damaged units "here" (wherever she currently is), if she's moved from the battlefield to base via Fight or Flight, the ability will resolve in base instead and heal damaged units there (if any exist).

Sequence:

• Janna is played to the battlefield (showdown)
• Her "When you play me" ability triggers and goes on the chain
• Opponent reacts with Hidden Fight or Flight, moving Janna to base
• Janna's ability resolves, but "here" now refers to base, not the battlefield
• If there are damaged units in base, they will be healed; otherwise the ability has no effect

Nuances:

• "Here" is not targeting - it refers to Janna's current location when the ability resolves, not where she was when played
• The ability always triggers and resolves once on the chain, but the effect depends on where Janna is at resolution
