I just said an hour in the event something took me longer than expected to decide on, I was already working on it before you sent your message. Realistically it should be finished within 20 minutes.
You should have read the tournament's list by now. Apparently, we should be against each other. I am free on Thursday, Friday and Saturday. I can battle you any other day as long as I am free, though. So, when can you battle? Give the time according to GMT please.
Since I have been away and I am currently in a chaos creating a team, I don't mind battling you when we find each other online. Regarding the server, probably Smogon.
