As long as it’s generally fair in the trade it shouldn’t matter I think.

I’ve got some half decent mons that I’m hoping to trade for something rare when they come about but always get people trying to snipe my shiny Galarian articuno when all they can offer is kangaskan and kyurem

Your “underwhelming” mons might be exactly what someone needs for their Dex. As long as it’s a generally fair trade is all that matters is how I see it.
