Fox-Fire

signature spell

[Hidden] (Hide now for rune rainbow to react with later for energy 0.) [Action] (Play on your turn or in showdowns.) Kill any number of units at a battlefield with total Might 4 or less.

Rulings

• Are the units I choose for Fox-Fire targets? What happens if some of them gain Might as a reaction?
• Does that mean if the units I originally chose die, move, or lose Might as a Reaction, I can pick additional units at that battlefield to kill?
