I'm a bit busy now, but if you haven't made your trades by the time I'm able to trade (4 EST) then I'll trade you either a larvitar or hippopotas for an Aron.
Saw your quick trade request for Lucario, but I have a Riolu caught with a luxury ball so it will evolve quicker. I would evolve it myself for you today, but it only evolves during the daytime. I have a Zoroark already, and really want a male Hitmonchan (or male Timburr) with Drain Punch and Mach Punch. I'd enjoy other pokemon too if you don't have it, but those would help me out the most.
