Summon Unhappy Girl, or Rai-Mei if you don't have unhappy girl, and stall until you can perform gravekeeper's vassal and union attack combo. Set a Rai-Mei when you set an Enchanted Javelin to raise your LP to ensure Tea won't attack the unhappy girl while also thinning your deck. Summon BEUD when you can before the last turn and leave 1 monster slot open for vassal.
Example deck (No Union Attack)
Works similarly to the method above, except the finisher is Cu Chulainn. Use the Rai-Mei to thin out your deck and summon BEWD early in the duel. Since Cu Chulainn's damage is only going to be around 5000, make sure to destroy her solemn wishes as early as you can, otherwise just deal the 5000 damage and get her to deck out.
For Tea you MUST have blue eyes ultimate dragon or master of oz as she has 2 traps cards that give her 500 life points every card she draws but for Yugi, Odion, Weevil and Rex you don't need a fusion monster, you only need gate guardian which you get at the beginning.
You could use something like this for Yugi, Odion, Weevil and Rex as they don't have cards that gives them life points but for Tea you must use something like the deck above as she gains life points. That max I've seen her have is 14k.
Don't worry, bro! You might be lucky enough to farm her cards less than 3 months. I wish Konami would add a feature that allows us to trade our extra cards with our friends on Duel Links. This would be very much helpful!
What really creeps me out are her eyes.. it's like she's going to tear your heart out while you're sleeping.
And talking about eyes: What the fuck's wrong with Vagabond's eyes? His hat is not covering his eyes, HE HAS NO EYES at all. Just look at where the shadow of his hat starts. It's exactly where the eyes of the other chars start! It creeps me out
When you got those sages stone, what character did you use and did you use their skill while playing that duel? It's literally the only card I haven't got and I beat teA over 100 times with over 6k duel assement. Is use guardian bau deck and the dropped me 5 supremacy berry and Dm girl before they give me 1 sages stone
I used this deck to farm Tea. It makes +/- 7k each duel (although I use six glossy cards to reach that score.)
The important part is to thin your deck faster than her, which can be the difficult due to her amount of draw engines.
The skill can be changed to Draw Sense: Low-Level, if you have that. The LIGHT variant will most likely not work because of the Thunder Dragons.
