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.
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.
uhm what? you can use almost any deck to beat her... we want to farm her not just only win the duel
Mai Valentine's deck changes. I just had a duel where she had 3 AMAZONESS VILLAGES!
I seriously cannot beat her and I am having a very hard time beating Mai Valentine. Like an extremely hard time. I do not have the cards for those decks for I am a new duelist and I started three weeks ago. I rarely win and I am trying to get the two SR Harpie cards, but it seems I have gotten every card EXCEPT, the Harpie cards. I need some serious help.
There can only be one effect per skill you stupid moron.
If it's a field spell skill, that's all there is. You can't use a skill that gives a field spell and also allow you to bring that field spell back from the grave. Skills don't work like that in the game.
