You said you need Simisear? I know they are a rustling grass in Pinwheel Forest inner area, and of all of them, that was the biyatch to find. I could breed a Pansear if that suffices. Also, Lilligant from Petilil, but I don't have a Sun Stone if you already have Petilil. Eelektross is the same problem, I have one and can breed them but I don't have another Thunderstone (or if I do I'll need it to get Raichu someday, or a Jolteon). Same problem with the Moon Stone, though that might be the one I can buy currently in Black City.
I do know they occur in Dust Clouds, and not having a player for getting Black City recruits from, it's my only way to get stones. If I find the applicable stones at some point, I know I need more White exclusive Pokémon. I'm not sure if you have any of my rather long list in the trade thread? Any number you're willing to trade I can always trade some SuperZoruas for (I'm breeding them with Night Daze already learned).
I'll simplify it. :) The Route 9 and Route 11 trade swaps are taken care of, and an Abundant Shrine one. So are the Clamperls ATM (I can confirm later 2morrow). So I'm offering you a Zorua with Leer/Foul Play/Faint Attack/Night Daze, and I can use Night Slash in place of anything but Leer (Leer replaced it in that first slot). If you want anything else, ask and I'll let you know, and let me know what you can offer for trade. Magby and Machop are expected in trades 2morrow, as is a Caterpie. That's the simple version. :)
