Some FAQs. The first one is take-it-or-leave-it, but the second came up at one point in the thread and definitely seems FAQ-worthy.
Q: If no other figure on the battlefield has a higher Attack number than Maxima, can Maxima still choose a Mate? What if the figure with the highest Attack number does not have the Super Strength special power? For example, if the only other figures on the battlefield are Captain America (6 attack, no Super Strength) and Scorpion (5 attack, Super Strength)
A: In both of those scenarios, Maxima cannot choose a Mate. When choosing a Mate, you must choose a figure that does not have a lower Attack number than any other Unique Hero on the battlefield and also has the Super Strength special power. If there are multiple such figures, you may choose any one of them. If there are no such figures, you cannot choose a Mate.
Q: Do attack boosts from figures like Bane or Star-Lord affect what units Maxima can choose as a Mate?
A: No, because Seeking a Mate references the Attack numbers listed on cards. When determining the Unique Hero with the highest Attack number, any special powers that add to or subtract from attack should not be taken into account. The only caveat here is Mister Sinister: because Sinister's Genetic Manipulation replaces the value on a card rather than modifying it, Sinister's power may influence who can be chosen as Maxima's Mate. If Mister Sinister alters a figure's Attack number, consider the altered value as the Attack number listed on that figure's card.
