Most of that user's post history is obnoxious like that, with a vague pretense of irony when called out.

Yeah, the whole "weird" thing reminds me of rewarding conformity and punishing what the majority perceives as "deviance", which is like queer theory 101 "don't do this"

Also it seems like Pokémon is a very mainstream card game these days. I see a lot of families with kids where the kiddos get cheap cards while mom or dad goes for the higher end stuff. It's becoming an intergenerational hobby kind of like sports cards.
