How to use this deck

Building a Labyrinth

Use the skill and special summon Labyrinth Wall when you have a Dimension Gate in your hand, shuffling cards that don't help you with draws into your deck. Once you have labyrinth on the field, and set a dimension gate, activate dimension gate right away on Kaiba's turn to banish your labyrinth, or activate it when Kaiba targets your Labyrinth with his Enemy Controller.

  • If you don't have dimension gate in your hand, use your other draw cards or set A Cat of Ill Omen to get it from your deck.
  • Dimension Gate is used on Labyrinth to protect it from Kaiba's Enemy Controller as well as his D.D. Warrior.
  • Since Kaiba doesn't have any attack increasing cards, his highest attack monster is his Blue-Eyes White Dragon with 3000 attack.
  • With Blue-Eyes unable to break through Labyrinth, enemy controller can't target banished monsters, and the AI not using D.D. Warrior to trigger dimension gate's effect, this setup essentially nullifies all 3 of Kaiba's threats.

The setup

After you have labyrinth on the field, you just need to banish it using Dimension Gate, then keep drawing the cards using Skelengel and Crystal Seer to speed up the process.

  • Make sure to use crystal seer's effect at least once, to make sure that essential cards are not the last card in your deck, by sending ones you don't need to the bottom of the deck.
  • If you don't have any draw cards, then just keep passing the turns.
  • When you have 1 card left in your deck, set your Spell Reclamation (if you use it instead of 2 Union Attack).

Last turn

Make sure that you use Storm first, before summoning your monsters. This is to prevent Kaiba from using his Enemy Controller on you.

  • Use Storm to destroy your dimension gate, as well as all of Kaiba's set spell/trap cards.
  • Use Temple of the Kings and then Double Summon to get your Vassal and fusion monster to the field (through Serket).
  • Secret Pass to the Treasures on to Vassal, and then double union attack, or 1 union + spell reclamation.
  • Equip your BEUD with Dragon Treasure, or any other attack increasing cards that you have.
  • Attack directly with vassal


  • While this deck does have consistent win rate, there is still a possibility of not getting dimension gate early in the duel, and using Labyrinth without dimension gate will most likely result in a fail due to D.D. Warrior.
  • This deck REQUIRES Dimension Gate, and it is only obtainable during Paradox Brothers' event. There are no other alternatives to the card, and having 3 in the deck increases the chance of getting it early, which is important.
  • Temple of the Kings can sometimes be buggy, and not allow you to special summon a monster, despite having monsters in your extra deck and/or hand. Be sure to check the in-game news if there are any issues still occurring about this, or if it's fixed.

Why does my Labirynth not work? On the last turn, i use secret pass on the labirynth wall and kaiba doesn't take damage. Nor am I able to perform other attacks

Union Attack does not allow Battle Damage for that turn. You have to use 'Grave Keepers Vassal' because that counts as Effect Damage. Will not work with any other monster and Union Attack

You can get the Vassal by leveling up Ishizu
What can A Cat of Ill Omen be replaced with?

In the comments are alternative lab builder decks that work and don't have the too many card on hand problem the sword and shield and the magic deflector one work both great
Kaiba uses twister on dimension gate so someone needs to update this.

Only happen when Kaiba already set twister before we activate dimension gate.

Regarding the use of storm to remove backrow. What is kaiba has set 3 backrow? All I can think of is to also set a field spell so you can remove all 3. Also, storm + spell reclemation does not work?

Use magic deflector against kaiba it can be obtained at the card trader so you won't need storm anymore

Usually, it's a mix between Twister, EC, and Cost Down
Works very well....20 duels - 20 wins
Just remember to do in the last roud:
1- use storm to clear the spell & trap card zone and bring your Labyrinth Wall in attack position
2- then use sword and shield
3- special summon The Fiend Megacyber
4- normal summon GK Vassal
5- done!

Replace two keto for one more cat of ill omen and one mooyan curry to get the low lp bonus

This is the shittiest farming deck ever! I did everything exactly like this Page said but every fucking time I have too many essential cards in my Hand so have to dismiss them and everything is broken - I tried bypassing this but there are too many key cards in this pile of shit!

HAHAHA you suck and you are stupid that's why you can't do it right! Try the Shield&Sword variant of this deck, if it still won't work, consider paying hospital fees for an upcoming brain surgery.

My way of farming level 40 kaiba it solves the too many cards on hand problem pretty well if you have another cat of ill omen switch it for one keto spellcard using BEUD as fusion monster

Hey guys, I have only one Dimension Gate and zero Cat of Omen (I could get one but it will take some time to level up Ishizu). So I was wondering: are there other alternatives? And if not, is it advisable to battle Kaiba with onl one DG or do I have to wait until the next Paradox Brothers event?

I would advise another deck, and if you insist on using this deck then you NEED 2 Cats of Omen. Dont even try otherwise. I think at least 2 dgate is mandatory, though.
