Can you play Find Your Center with its reduced cost when an opponent goes from 4 to 5 points by conquering an empty battlefield?

Ruling: You cannot play Find Your Center with the reduced cost in this scenario. If the opponent doesn't start another showdown after scoring their 5th point, there is no opportunity to play it during their turn.

Sequence:

• You can play Find Your Center when the combat starts, but at that point the opponent is still at 4 points (not within 3 of victory)
• Once they score and reach 5 points, if they don't start another showdown, you get no further priority during their turn

Nuances:

• The cost reduction requires the opponent to already be within 3 points of victory, so you need them at 5+ points before you can use the reduced cost
• There is no priority window between them scoring the 5th point and the end of their turn unless they initiate another action
