After some waiting, searching, and deal-making, I am still trying to obtain an Ability Capsule. I can offer plenty of things in exchange for it, including most Pokemon, various items, Pokerus, and almost any Mega Stone which could be obtained in X and/or Y, with the exceptions of Garchompite and Lucarionite, although I am attempting to get the latter. Given enough time and assuming I have access to the correct materials, I am also willing and able to breed Pokemon with certain specifics such as Natures, Egg Moves, etc.
I would like to make a full, detailed list of what I can offer, but that would require significant stock-taking, an understanding of what others on this forum consider valuable, and enough typing to give me carpal tunnel for a month. If interested, simply reply here or through PM, and we can negotiate.
On another note, I am in possession of two Eviolites which I obtained for the purpose of trading them to someone else in exchange for an Ability Capsule, but the person I intended to trade with has yet to respond to my offer. Therefore, I am willing to offer said Eviolites amongst the varied objects I can pay with.
EDIT: Trade completed
