What I have comprised below is a sure-fire (if not) way to a one-sided match where you are controlling the shots. With life absorbing machine active you gain half of the life points you paid from a previous turn. Imperial Customs protects all Continuous Trap cards excluding itself. Activate Final Countdown and don’t worry, you will regain 1000 LP in your next turn from this payment of 2000 LP. With Tour of Doom you can either prevent yourself or your opponent from flip summoning or normal summoning by the dictation of a flip of a coin. You want the ‘heads’ result, and that prevents your opponent from normal summoning and flip summoning. Second Coin Toss allows for you to re-do a coin toss, negating the prior toss. Royal Oppression disallows your opponent from special summoning at the cost of 800 LP each time they special summon. You gain 400 LP back on your next turn from Life Absorbing Machine. Light of intervention disables their ability and yours to set monsters on the field. With tour and Intervention alone the only thing that your opponent can do is special summon, but the answer to that is Royal Oppression.
The desired combo though is: Imperial Custom, Tour of Doom, Light of Intervention, Royal Oppression and Second Coin Toss. Of course be sure though to activate Final Countdown first, and if you want to activate the Life Absorbing Machine to gain back half of the paid LP from Final Countdown you will have to get rid of it to make room for the other cards. I suggest double cyclone to get rid of it. With the normal spell card double cyclone you can destroy one spell/trap card on your side and destroy one spell/trap card on your opponent’s side.
I hope this helps!
