Currently, the teambuilder seems to validate sets containing two entries of the same moves, only to show only one of it in battle time.
I feel like teambuilder should reject if a Pokemon has the same moves more than once, so that the person building a team has a chance of rectifying it instead of finding out to his surprise that he has less than four moves available at his disposal.
