Use The Unhappy Girl with Tea's "Holy Guard" skill to prevent any damage taken when you attack and stall for turns.
Bring some recovery cards to maintain your LP.
Example deck (No Union Attack, LP α skill)
Using the skill LP α, Mai won't attack the unhappy girl unless she summons high attack monsters that can deal 5000 damage after attacking unhappy girl. Either raise your LP quickly by using enchanted javelin and set a monster to bait an attack, or bring equip cards to increase unhappy girls' attack. Stall using the unhappy girl and don't summon BEWD until the last turn. Tribute summon and ritual summon on the last turn and use secret pass on Cu before increasing his attack.
Special summons an Amazoness monster from the graveyard without cost.
How to defeat Mai's deck
Remove Amazoness Village first
Mai's side of the field never become empty while the Amazoness Village field spell is activated. To allow your monsters to attack Mai's life points directly, you should destroy the field spell and prevent amazoness reinforcements from being special summoned.
Use Tea and her skill Holy Guard together with Unhappy Girl deck

"Guys any suggestion on how to simply beat her? I mean im on stage 49 and I only need to beat Mai and Ishizu and both are completely destroying me..."
Lol.Same (almost) mai's the last one for me to beat in terms of mission/level requirements and she is indeed a major struggle to beat. Doesn't seem to matter what you do, she seems to have a way around things.

If anyone of you meet quick victory against mai I suggested joey with 3 karate man the equip that let you attack twice draw cards and the card that let 1000 and less attack directly
No, they patched the ability to reset LDs that appear in Duel World. Quitting against her before you lose will maintain your streak. I just completed the "win 3 consecutive duels against lvl 40 Kaiba" with this method.

Pretty sure they patched that

Does anyone have a sugestion on how to beat Mai for the stage 59?
You have to do a quick victory with Joey 3 times.
I'm finding f.. impossible
Using Tea with Holy guard skill.3 Unhappy girl and keep attacking his monster, 3 of Rai-Mai to pull out Unhappy girls more easily and 3 bubonic mumin to fun your deck and good defensive cards. Other 11 cards to finish Mai depend on you

This Deck works very well for me. Just boost her monsters above 1900 ATK and you are safe. Easy win.
