Yeah, exactly.
Luvdisc are probably the absolute worst, yeah. Because 999 of every 1000 of those wonder-traded are going to be from someone who caught it for a heart scale. So these are people who know what they're doing when they send it out.
At least when it's stuff from the beginning of the game, maybe it's someone starting a Wonder Trade Nuzlocke, maybe it's a kid, etc etc. There's basically no room for that with a Luvdisc; it's someone knowingly sending out their trash and expecting to score good Pokemon in return.
Edit: Though actually I guess I'll try to help make some lemonade out of lemons here and grab that Pichu off you to try and troll my friend with it. We've traded before, right? Forgot what I gave you last time. Currently breeding Moon Ball Hoothoot with Whirlwind, Night Shade, and Feather Dance, but also have a small collection of other stuff with egg moves/HAs.
