If my opponent Charms my unit to their battlefield, then I use Ride the Wind to move it back to my original battlefield, do I score a point?

Ruling: Yes, you will score a point for conquering the original battlefield, assuming you didn't control it when the showdown begins and haven't scored it yet this turn.

Sequence:

• Opponent Charms your unit to their battlefield (battlefield B), opening combat there and causing you to lose control of your original battlefield (battlefield A)
• During the showdown step of the combat at battlefield B, you play Ride the Wind to move your unit back to battlefield A
• This stages a showdown at battlefield A
• When the combat at battlefield B finishes, players can perform actions
• If no players perform other actions, the staged showdown at battlefield A begins
• If no players perform other actions during that combat, you conquer battlefield A and score a point

Nuances:

• Players have opportunities to play spells or activate abilities between combats and during the staged showdown
• You must not control battlefield A when the showdown begins to score the point
• You must not have already scored battlefield A this turn
