>>39570475I pulled a Tentacool from Shalour City (wasn't sure if I should count it separately from Tower of Mastery or not, but went for it anyway) and a Magikarp from Parfum Palace, which I just now learned you could actually fish from.
The last Eevee would normally come from a trade you would have with the hotel maids, but I just caught one in Route 10. Of course I did catch something on that route beforehand, but for the sake of simplicity and not resetting my 3DS clock four times, I just did this. It took about a day's worth of grinding (Day Care Center is a life saver) and now I'm just about ready for the Elite 4.
This is quite literally everything I have left. No more routes, and no more alternative options. My last hurrah, this is the endgame.
