I'll be on for about an hour on or so from here. I added your FR (from your sig.) Though I'll be on 12 hours from now also.
EDIT: Someone just traded me a Thick Fat Swinub (I forgot to take it out of my profile.) I can still trade, 'cause hey, a deal is a deal, but if it's okay with you, can we trade for a HA shellder/gligar/natu/riolu or a regular chansey/shellos? Again, nature/IV's don't matter. If not, well, swinub it is.
Sorry just read this edit. Unfortunately my only copy of those pokes you mentioned are the 5IV ones I use for battling. I could offer you a couple other spitbacks though: 4IV regen slowpoke, 5IV slowpoke w/ wrong ability, 5IV diglett w/ wrong ability, 5IV swinub w/ wrong ability (if you want to breed flawless ones), and 5IV frisk phantump
