I can trade for any of the things that you wanted. I have all three of those pokemon too. I am also looking for umbreon, espeon, qwilfish, slakoth (or any of its evolutions), and lunatone.
I have Umbreon, qwilfish, slaking and lunatone. How about salamence, Latios, and any other four you want that I have, for manaphy, jirachi, darkrai, froslass, mismagius, and shaymin.
If there is anything else you don't have tell me I might have it. Also if you want to adjust my offer just tell me.
Edit - I also have all of the fossil pokemon except for shieldon/bastiodon so if you have shieldon/bastiodon or need any fossils we can trade
