Like @DFBB said make sure you save it first so that you can log back into the same team if you change your mind. You should know that with a new team you won't keep any of your resources, gold etc... So you're pretty much limited to drafting 5* players only and can pretty much forget about legends & primes. Unless if you plan on staying bronze in which case you may be able to get enough LXP & PXP here and there for a few players at least.
