Does the cost reduction text on Find Your Center apply twice when the spell is Repeated with Temporal Portal?

Ruling: The cost reduction only applies once. When you pay the Repeat cost, you pay the base cost (3) plus the Repeat cost (3) minus the single reduction (2) for a total of 4 energy, then execute Find Your Center's effect twice upon resolution.

Sequence:

• Declare you are casting Find Your Center and paying the Repeat cost
• Calculate total cost: 3 (base) + 3 (Repeat) - 2 (reduction if opponent is within 3 VP) = 4 energy
• Pay the 4 energy
• Upon resolution, execute Find Your Center's instructions twice

Nuances:

• Cost reductions are passive abilities that apply during the cost determination step, not instructions that execute upon resolution
• The Repeat keyword specifically states the effect is performed an additional time "upon resolution," which happens after costs are paid
• Cost reductions like Skysplitter can still reduce the combined Repeat cost if the reduction is large enough (e.g., a 16 might unit would make an 8-cost spell with Repeat free)
