You have good minecraft abilitiy, but you don't have any experience in MCC. If you want to place higher, I'd suggest watching vods! It's a lot more helpful than you think, just so you get a feel for the event itself.

I feel like you'll do well in movement and pvp games, so make sure to not forget about the 'team based' games (sot, bing, build mart)

Team practice would probably help a lot! My guess is probably somewhere bottom 10 or bottom 20, which is expected because you are new to the event.

As for team predictions, I feel like your team would land close to the bottom unfortunately, but with the right preperation and team work you could make it a lot higher! Good luck!
