How much do I pay for an Accelerate cost?

Accelerate costs 1 energy and also 1 power of the unitʼs domain/color. Usually youʼll do this by taking an additional ready rune of the appropriate domain/color, exhaust it, and then recycle that same rune. For example, if a fury/red unit normally costs [3] (or 3 energy) and you want to accelerate it, its total cost would be [4][R] (or 4 energy and 1 power of the fury/red domain).
