Best Arena #1 Holding Squad

The only way to do this is to run a strong squad (and there are many) and be a jerk. You have to camp other peoples payouts and constently fight all day to defend 1st. If you really want to be obnoxious, actively lock people (that can easily beat you and do 99% of the time) out at their pay out and spend 400 crystals every day doing it. Sounds ignorant doesn't it? It happens on a good fair amount of shards.
