First, put Blue Eyes Ultimate Dragon in your deck. Then, put a Cyber Stein in your deck and duel. When you draw Cyber Stein, make sure you have much more than 5000 LP, then play it. Next, press A on the Cyber Stein and select "Activate". You will lose 5000 LP, which is a small price to pay to special summon Blue Eyes Ultimate Dragon.

You need a Monster Reborn and a Magic Jammer. When you activate the Magic Jammer card, discard the Blue Eyes Ultimate Dragon, then use a Monster Reborn to get it back on the field, with no cards getting sacrificed.

Have a deck with a Blue-Eyes White Dragon, Ring Of Magnetism, and a Sword Of Deep-Seated. Summon the Blue-Eyes White Dragon and use both the Ring Of Magnetism and the Sword Of Deep-Seated. If any of your opponent's monsters attack the Blue-Eyes White Dragon it will destroy itself while losing life points. Note: If your opponent uses a magic card to destroy the magic cards, this trick will not work.

Have a Lord of D. and three Blue-Eyes White Dragons out on the field. Do the same thing to one of the dragons and your opponent has one monster card in attack mode. You can use the other three monsters to attack his/her life points.
