  • Gemini Elf can be replaced with Neo the Magical Swordsman or Mist Valley Watcher. Legion the Fiend Jester can be replaced by Blue Dragon Summoner.
  • Stall the entire game with Labyrinth Wall.
  • While stalling, try to deck out as quickly as possible with your draw effects.
  • Use Wonder Wand on your Gravekeeper's Recruiter or Blue Dragon Summoner, this way you can draw more cards from your deck and fetch another monster from your deck.
  • Use White Elephant's Gift to send Gemini Elf to your graveyard and draw 2 cards. Remember to keep at least 1 Gemini Elf in your hand for your final turn.
  • During you final turn, put Labyrinth Wall in attack position and then activate Shield and Sword before summoning Gemini Elf. Then use Double Summon to summon Gravekeeper's Vassal.
  • If you are using Mist Valley Watcher summon him first before using Shield and Sword.

  • Summon Ojama Knight or Ojama King as early as possible. They have enough defense to stall Mai's strongest monsters and with 0 attack Mai cannot use Amazoness Fighting Spirit to boost her attack.
  • After that just keep stalling until you deck out. Ojama Blue and Jar of Greed helps you get Ojamas out of your deck, King of the Swamp helps you search Polymerization in your deck. You can also use these cards to help fusion summon Ojama Knight earlier, if you have not yet.
  • During your final turn, have 2 face-up attack position Ojama Knight then use Ojama Country. Normal Summon Gravekeeper's Vassal then use Secret Pass to the Treasures and 2 Union Attack on him. Direct attack for over 9999 damage assessment.
  • Restart is only for consistency boosting. This deck can work without any skill, so you can use it for skill farming.

I used the Ojama deck with labyrinth builder. The problems I faces before this skill change was that restart is now needed and so if you don't get what you need, it's gonna be tough. However with the labyrinth skill you're just recycling the cards and can stall until you get them back.

The Ojama Deck worked perfectly
In case people still looking for easy fa deck, you can easily farm her with Labyrinth Buider.

Ironically, you need to farm to get Lab Builder. Use Elements unite instead because she doesn't have anything against it at lvl 40.

Element united's deck is very bad if you don't recover your life point as fast as posible you could lost with amazoness archer since there are amazoness village it'll be useless to destroy her monster.

Thanks for suggesting.
I am going to go with (2) gift of the martyr (1) riryoku.
but seriously what is use of piranha army in a farming deck.
<< Anonymous
akubane Reply
piranha is for the 10k damage. summon piranha, use pass, use riryoku, play gift or 2 and attack with double combat damage.

Not that I know of.... You COULD use a form of unity THEN use something along the lines of shield and sword/ojama country

You can farm Yugi Moto for it, you know. don't have to get it from event
Confused AF 20days ago
So i tried out the lab builder, and for some reason, whenever Mai puts out Amazoness Archer, if she doesn't activate it's effect to damage you, it beats her to death against your wall

Ojama works great. I got 2 swords woman. Luckily, I didnt waste my SR tickets on them.
No Union Attack
Double Riryoku

Screw you. I've been farming since May last year and still no Sage.
Ojamas work flawlessly. Don't use land of the ojamas skill. Just put ojama country in the deck. Last turn, put king and knight in attack position, activate field spell, vassal, unionn att, and ama.

Not entirely sure how consistent it is but it does work if you can get either of the fusion out before Mai gets a full field of monsters. I got 7,000-7,500 duel score with this so far.

I used labyrinth to farm Mai

She attack the Labyrinth Wall using Amazoness Archer and suicide.

Why the hell did she do that? LMAO
Sylvans Ra works. You just need to remove Fighting spirit.

Sylvans with Ra. Yami Merricks "Power of the tributed" ability.

Stall until last cards in deck and then summon Ra + activate effect to have over 10,000 attack if you don't take any damage which is ez with Sylvans high attack units. Clear her field throughout the fight so she can't tribute summon.
