I want to give an improvement to the Labyrinth Builder deck above. Amazoness Sage is a problem for the current build for two reasons: if you use Shard of Greed, she will attack your Labyrinth Wall, costing you the effect damage only bonus, and the final 10k damage combo has too many cards you need to keep until the final turn (2x union attack, 2x thunder dragon, secret pass, shield and sword, gk vassel, and that's 7) so you either have to set a card which Amazoness sage will destroy or finish the farm early costing you the no cards left bonus.

This version is also 8k base without glossy or prismatic bonuses because of the tribute summon. In this version, you want to search for vassal early with recruiter and wonder wand and then discard it when your hand is full or use it with wonder wand to get it into the graveyard. On the last turn, tribute labyrinth wall for chief to bring back vassal, fusion (have fusion gate active ahead of time), secret pass, union, union, attack. That's only 6 cards needed that you can't discard instead of 7 (chief, 2x thunder dragon, secret pass, 2x union attack,

The double summon is just there since it can speed up the farm sometimes by using two wonder wands in one turn or you can use wonder wand and tribute for chief in the same turn.

Important things for either version to know: you can "toggle on" to use jar of greed or legacy of yata-garusu before amazoness sage can enter the battle phase, and Mai doesn't try to destroy fusion gate with amazoness sage.

Use the same deck against Yami Marik for Mai. The Cerberus deck works like a charm.

FYI - for stage 57, I used Paradox Bros and a modified Elements unite deck (with healing and damage effect cards) and easily beat Mai 3x in a row.
I used this Labyrinth Builder Deck against Mai. No traps & no Serket. 100% winrate so far.

Monster (16)
1x The Fiend Megacyber
1x Gravekeeper's Vassal
3x Thunder Dragon
3x Crystal Seer
3x Bubonic Vermin
3x Skelengel
2x Dark Mimic Lvl 1

Spell (4)
2x Union Attack
1x Secret Pass to The Treasures
1x Shield & Sword
