• As you unlock cards replace the weaker cards in your deck with stronger ones. Ideally at the start 900 ATK+ to help farm quicker.
  
• Defeat Yugi, Bakura, Joey, and Tristan 5 times each. If you lose count you can check in "Records"
  
• Continue to fight Joey until you get at least 2/3 Legendary Swords (Guaranteed 1 after 20 wins).

You can fuse monsters that are eligible by placing one material on top of the other when summoning them onto the board.

Joey is one that you can mindlessly grind with 900+ ATK decks in a quick manner and gives you a structured deck that can get 1800+ ATK almost guaranteed with buff cards.

I was able to beat Kaiba with only 20 wins against Joey. Looking back I was wasting time farming other duelists another 20-30 times. However, if you're not as lucky as me with some of my drops you're guaranteed some strong warrior cards if you dont get lucky with the drops.

Once you get a strong deck of Warrior and buff cards you are all set to face Kaiba. If you aren't the type to restart duels until you get the perfect start you still can farm everything you need other then a 2k defense monster from Joey.

If needed farm Yugi for "Mystical Elf" (2000 Def) to get a strong defense monster to stall a duel if needed.

Build your deck for 3 things

1. High Defense (any type) - Use these in case Kaiba has a strong start to stall.
   
2. High Attack (Ideally Warrior) - Use these to either fuse a Flame Swordsmen and buff if possible or buff other warriors.
   
3. Raigeki & Buff cards like Sogen & Legendary Sword (2+)

You will NEED to be able to deal get over 2000+ ATK

You have 2 options

• Restart the fight until you're able to get a starting monster that doesn't die and you can buff turn 2 then steamroll (You'll want attack higher then 1800, if not higher)
  
  
• If you dont want to just restart and dont have the best start, use Def Monsters to stall while you wait to use raigeki or black holes to get a foot hold. OR stall out the duel and use Direct Damage spells to make sure you Life Points are higher at duels end.

Kaiba's deck is randomly generated each match. Here are some cards you will hope you dont see

• Blue Eyes White Dragon - 1.22% Chance (3000 ATK)
  
• Judge Man - 0.49% Chance (2200 (ATK)
  
• Rabid Horseman - 0.63% Chance (2000 ATK)
  
• Roaring Ocean Snak - 0.29% Chance (2100 ATK)

The NEXT highest cards are 1800 ATK. Once you're over 1800 ATK you're almost guaranteed a win.

Depending on how the run is going prior and what you got buffed already, these won't always be an issue even if encountered. On my run I got my monster over 2500+ and never saw a Blue Eyes.
