You don't see offers very much (in a given day the level 1-10 category will have about 2, I assume any other levels to be a lie, especially the 10-20 wild range) and I can certainly see the demand (useful in battle spot, can't get without an event Pokemon). Given how they can be mass produced (do the same thing you did for mine except with 5 Smeargles in the party, possibly breeding with both parents having the move but that might only work for level up+egg movesy) and people are weary of GTS scams the market is probably not that sustainable.
Might be something I'll think about. Been meaning to breed some Smeargle's anyway. Once I finish up my Modest Charmanders, I'll probably hop in. Gotta do a little research into the abilities. I noticed yours had Moody. Moody seems like a crapshoot, but I guess it has it bonuses if it aligns right?
Looking on Serebii, Smeargle doesn't have egg moves, so would imagine I couldn't simply just breed them, but would have to go in each time. Not that it costs much to do, only time. But sounds like it could be interesting to throw up on GTS.
I don't know. While there are many liars on GTS, I tend to add correct notes to my Pokemon such as "5IV Timid" or whatever is applicable and never have a hard time getting rid of those Pokemon. Course it could depend on what you're throwing up there. I might dabble in it a bit this weekend to see how the market is.
And while I mark mine appropriately, I've never gotten a Pokemon that was appropriately tagged, so I've given up on it. Tired of trying to get HA things and you get it and gee no HA. But that goes for anything. Folks don't even read my notes. But that's why I try to be accurate on ones I do put up. To try to at least restore faith for those who do go on my notes.
Edit: Actually, reminds me, I should look into Happy Hour Smeargle's too to see if they're worth the time.
