The rules say charater's abilities that affect Crisis Cards do not work vs Super Crisis cards.
Almost all of the character abilities say, explicitly, Crisis Card and "target" the card.
Galen's once-per-game ability targets a skill check and specificly the cards therein and makes no mention whatsoever about anything about a Crisis Card.
Can it target a skill check generated from a Super Crisis card?
Seems sort of a grey area....
now ? - as the ability does not mention crisis cards at all but just skill checks (which may not even be on a crisis card), as opposed to six other characters which has crisis card mentioned on their card, then the passage from the rules
"Super Crisis Cards are immune to character abilities that specifically affect Crisis Cards."
just does not apply.
