Yeah, true, but "exploit a comparative advantage" is a template characteristic. If there was a card representing the template as a whole instead of each individual one of them then it'd definitely be Blue-Black. It's each individual that I think is a bit more nuanced; from an individual card mechanic perspective, once they have a comparative advantage to exploit they'd just use it.
Like, Sparkles-as-a-card would have some mechanic that would feel very Simic, probably, biological manipulation. The others are not as obvious, I could be convinced that Wix is Blue-Black as opposed to Blue-Red, Octarine and Prop aren't exactly Azorius but it feels like they're either that or monoblue, and Glam hasn't had a chance yet to appear anywhere so I'm only guessing about their colour.
