What the pet? prismatic harpie dragon and d draw? What are the odds?!
Red-Eyes + Cards of Red Stone + Crystal Seer + Skelengel for draw power, Mai will always have 3 monsters if you don't attack any so special summon fiend megacyber last turn, sacrifice labyrinth wall to ritual summon Cu Chulainn, remove a red eyes from play to get its attack to 2900, then perform the Gravekeeper's Vassal combo to get up to 10.8k attack.

100% win rate will get you 7k every duel with glossies/prismatics.

I made a less complicated farm deck that goes quick enough and super cheap.

I hate this! It doesn't matter what I do. Smaller deck with lots of spell removal/prevention almost NEVER works because I keep getting crappy hands with her! I guess I should use Balance, because she almost ALWAYS gets both the village and fighting spirit on the first turn to get a crapload of Amazons on the field who keep coming back to eff me up! Why the hell is she so much harder than the other LDS!? I'm sorry, but I just needed to rant.

Thanks. I tried farming her with a Blue-eyes deck today. Only to get...another Harpy Lady Phoenix Formation. So I guess I might as well try something different and just hope that she gives me some Amazoness rainbow packs for once. XD At least I am almost done now due to the tickets.

Of course I already know that. Joey is the one who has Metalmorph as a drop reward, not Mai. I want the Amazoness cards because I want to try using an Amazoness deck. Besides, I don't need anymore Metalmorphs. I already have three of them.

Ojama Knight without ojama country completely shuts her down she can't get bigger then it and depending on the only creature she can usually set will not interact with your knight

I’ve found that the Dark Paladin farming deck is useful for this one. Since the highest possible attack is lower than Dark Paladin’s original attack, if you can get it on turn one, your victory is practically assured.

Regarding the labyrinth deck.

Its better to take out spell draw spells like shard and trap draw spells,
because her sage attacks into labyrinth wall if you have some in your spell trap zone
And that will make you lose1000 effect dmg.

You can replace them with crystal seers and other monster draws + go with 3x wonder wand spell.

Pick up lithograph too to make sure you can hold all the needed cards.
You can remove the curry spell.

Try keep the essential cards in the deck so you dont have to throw away/set an important spell trap as her sage will destroy it.

You can manage this with crystal seers choosing and by not using your last gravekeeper for vassal so he stays in the deck as long as possible.

Hope this helps some people.

Also an option is replace the fusion with the fiend megacyber. This way you wont have over 7 essential cards and thus no worries of getting too many cards in your hands. You can fill in the empty spots in the deck with the anything useful + the new Typhoon trap that you can use from your hand instantly. Giving you the used a trap score, without worries about her sage.

Is the archer a problem when using labyrinth builder skill?

Got a prismatic ;>
For some reason, I feel like I hardly ever get green keys to challenge her these days, and I don't want to use the card trader for them too much. Does anyone know a good way to get more green keys, or is it just random?
