Deck Strengths
  • Fairly cheap, the majority of the cards are easy to obtain event cards or draw cards. The only pack card that's 100% necessary is Gravity Axe - Grarl. 
  • Fast, once Lab Wall is equipped with Grarl, all you have to do is activate your draw cards. 
  • Needs only one card to stall out Yugi in most duels. 
Deck Weaknesses
  • Gravity Axe - Grarl is a must-have card, if you cannot open it early enough, Yugi can remove your Lab Wall easily. 
  • Yugi will sometimes summon a 3500 ATK Valkyrion, necessitating the use of another equip card to boost Lab Wall's defense. 
  • There are a lot of cards in the final turn combo; smart use of Good Goblin Housekeeping is helpful to put combo cards on the bottom of the deck. 
Deck Summary

Yugi Muto's level 40 deck is difficult, packed with challenges that can stop a farm. 


  • Sphere Kuriboh can stop your final attack
  • Guardian Sphinx and Golem Sentry can remove your monsters
  • Order to Charge is non-targeting monster removal
  • Valkyrion's 3500 ATK defeats standard Lab Wall

The biggest threats by far are the flip-flopping Golem and Sphinx, which are dealt with using Gravity Axe - Grarl. Equipping Wall with Grarl prevents them from flipping face up, and a strange AI quirk means that they won't use Order to Charge on the Lab Wall. The only thing left is some kind of defense booster for Valkyrion, Horn of the Unicorn is preferred since it's searchable with Iron Blacksmith Kotetsu. 

TL;DR Summon Lab Wall, equip it with both equip spells. 

Final Turn:

Be careful about managing your hand for the final turn, the kill combo is 8 cards, so setting Shield and Sword before the final turn and stacking combo pieces with Good Goblin Housekeeping is required. 

  • Activate Shield and Sword (putting Lab Wall at 4200)
  • Summon Vassal and activate Secret Pass + 2x Union Attack. 
  • Use Exchange, ideally exchanging your Kotetsu for Yugi's Sphere Kuriboh.
  • Equip a 2nd Horn of the Unicorn to Lab Wall, then attack for game. 
Core Cards
Card Explanation

Grarl is key to stop Muto's flip monsters, without this, he can remove your Lab Wall easily. 

Mandatory 2-3 of, 3 preferred. 

Unicorn boosts Lab Wall to 3700, putting it out of range of Valkyrion. 

Run 1-3.

He searches both equip spells and acts as a chump blocker, which is a huge consistency boost for the deck. It's also worth noting that Muto's AI likes to take Kotetsu with Exchange, so it's ideal to leave one in hand for the final combo. 

Run 3.


Exchange is key to make sure Sphere Kuriboh can't stop your final attack. 

Only one is required for the final turn.

Replacement/Tech Cards
Card Explanation
Acidic Downpour

This card can potentially replace Horn of the Unicorn, but it's more difficult since the ATK reduction gets in the way of the final turn combo. 3x Horn of the Unicorn and 1x Jar of Greed can be replaced with 2x Acidic Downpour, one Storm (to remove it), and Fiend Megacyber.
