Next month is going to be a month full of serial code events, given the next monthly mythical Darkrai will also be coming. Serial codes are annoying, but we have to deal with it.
Are they that annoying? Sure, they're a touch more effort than just wifi, and if they're restricted to picking up the code from a store then that is annoying, but if the code is given over the internet then it's fairly simple imo.

I'm so happy to finally get Hoopa was able to get two of them with both of my ORAS games, shame you can't trade them on the GTS wouldn't mind getting my hands on a Mew without the whole friend code exchanging
