This question has been brought up with previous cards. Basically, in at least some English Grammar books, including the one that AW goes by (whichever one that is) when you have an adjective followed by two nouns like this, the adjective applies to both. It's considered normal English because that's the way the English Grammar books teach it, but even to native English speakers it is not the most intuitive rule (I don't know if you're a native speaker or not, but I am and I was also confused by it).
Still, the answer to your question is that it applies to both. All other similar situations you find in the game also work the same way. Living creatures and conjurations means living creatures + living conjurations. Holy creatures and conjurations = holy creatures and holy conjurations. etc.
