It's almost as if ITC doesn't care what you bring or how you play as long as you stomp your opponent into the ground and max your points... Sportsmanship has no bearing on your W/L except to be such a jerk that your opponent makes mistakes and you score more points. Why score army composition when the goal is to smash your opponent with the hardest stuff in your army? Everyone is going to bring the same meta lists anyways, so comp scoring is useless.
The ultimate play (

move) would be to max your points in the first game, and at the bottom of turn 5, tell your opponent you concede.
