If I'm playing Vex in combat and use a 2-cost spell targeting a unit with Deflect, how much should I pay?

Ruling: You pay 1 Energy total. The spell's base cost is 2 Energy, Deflect adds 1 Power as an additional cost, then Vex's discount of 1 Energy and 1 Power reduces the total to 1 Energy.

Sequence:

• Start with the base cost (2 Energy)
• Apply additional costs like Deflect (adds 1 Power, making it 2 Energy + 1 Power)
• Apply discounts like Vex's ability (reduces by 1 Energy and 1 Power)
• Final cost: 1 Energy + 0 Power = 1 Energy

Nuances:

• Vex's ability only applies to friendly spells, not units
• Discounts can be applied to additional costs, not just base costs
• Vex's minimum of 1 Energy applies only to the spell's base cost, not the total cost including additional costs
• Deflect is a mandatory additional cost that must be included before applying discounts
