If I control Vex, Cheerless in combat and my opponent is at 6 points, can I play Find Your Center for free?

Ruling: Yes. Both Vex, Cheerless's discount and Find Your Center's conditional discount apply to the total cost of the spell, not to a specific component. You may apply them in any order you choose.

Sequence:

• Start with Find Your Center's base cost of [3] Energy
• Apply Vex, Cheerless's discount: reduce by [1] Energy to [2] Energy
• Apply Find Your Center's discount (opponent within 3 points of Victory Score): reduce by [2] Energy to [0] Energy

Nuances:

• When multiple discounts apply to the total cost (rather than to specific components), you may order them as you like to minimize the final cost.
• This only works when Vex is YOUR card; if Vex belonged to your opponent, it would increase the cost instead of decreasing it.
