Judgment Colosseum Lockdown

You will need:
 * Judgment of the Desert
 * Kaiser Colosseum
 * Swords of Revealing Light
 * Swords of Concealing Light
 * Any monster card

For this lockdown to work, your opponent must have at least two more monsters than you on their side of the field at all times.

First, set Judgment of the Desert.

On your next turn, summon a monster if you have none on the field. Activate Kaiser Colosseum and Swords of Concealing Light, then flip Judgment of the Desert. Finally, activate Swords of Revealing Light to flip all your opponent's monsters into face-up Defence position.

Now, due to Judgment of the Desert, your opponent's monsters cannot switch to Attack position. Thanks to Kaiser Colosseum, your opponent cannot summon any more. As long as you have at least two fewer monsters, they cannot perform any double Tributes, because that would have a net result of more monsters on their side of the field than yours.

Now, if you have a monster that can attack your opponent's Life Points directly, you can simply keep attacking. Rocket Jumper, Shadowslayer, and Black Tyranno all work well in this situation.
