Hallucination: You may resolve the effects of a fate card not named Hallucination in any edge stack as if it were revealed in your edge stack. If the Balance of the Force is with the dark side, resolve the effects twice instead.
Allies of Necessity: You may target 2 participating units you control that do not share an affiliation. If you do, one targeted unit gains [Unit Damage] and the other gains [Blast Damage] until the end of the engagement.
If the Dark side player does not have two units that do not share an affiliation, can they still trigger Hallucination to gain the icons, assuming they have 2 units. Could they trigger it to gain one of the icons, if they only have 1 unit?
