Bro, when you farm 4 times and get no platinum packs, it is better to stop farming and try later.

You want 7K guaranteed that can be used by any character with skill alpha (+1000 life points)? Now that Mythical Beast of Serket + Temple of the Kings activation has a bug doesn't work anymore, this is a great replacement.

1 x Des Kangaroo
1 x Big Koala
1 x Polymarization
1 x Black Pendant
3 x Rai Mei
3 x Unhappy girl
3 x Javelin
2 x Union attack
1 x Dian Keto
1 x Supremacy Berry
1 x Gravekeeper's Vassal
1 x Windstorm of Etaqua
1 x Secret Pass To The Treasure

make sure you attack his tiger and his amazon monster that can destroy spell/trap cards if it attacks and survives with your unhappy girl

Well not guaranteed, but if you don't get an unhappy girl or a Rai Mei on your first or second turn, then your luck is extremely bad

Thank you so much. Lost a few matches getting greedy trying to go for tribute summon bonus and low LP/LP on the brink bonus and otherwise dumb misplays. Other than that I'd say almost 90% win rate, at some point you get a bad starting hand and she opens up with her strongest combo. Almost 4 of every SR except still no Sage, and no Labyrinth Builder skill drop :/

Hopefully he'll be unlockable during the Marik event by reaching certain amount of point
what do you mean? are you feeling alright?
2 is ok. But 3 makes it more consistent. The you could replace card if the souls for a third.
