Mm, wouldn't be interested in that nature, sorry! I've decided to make all SPA/ITA Pokemon 0.5 credit, so if you want to try to negotiate something with those let me know what you have access to!
Understandable about the nature, Lonely actually kind of sucks as a nature anyhow. Adamant is where its at for a physical attacker anyway.
To answer your other inquiry, I have an extensive list of SPA Pokemon with a few ITA thrown in the mix. If you're interested, I am willing to offer any or all of them for trade:
ITA: Vullaby, Snorunt, Gastly, Pikipek
SPA: Squirtle, Grubbin (x2), Rowlet (x3) , Igglybuff, Finneon, Bewear, Klinklang, Granbull, Eevee, Cutiefly, Absol, Petilil, Mudbray, Yungoos, Ekans, Comfey.
If you need specifics on a particular one, let me know and I'll get it to you. But they're all fair game of you want to trade for any.
