This deck is just two META deck, facing each other (Salamangreat and Orcust). In one match, you can change your playstyle to the other deck.
Strategy:
As I said, you are playing META. But it's harder because you will have 25 support card in your main deck, and the other 15 card is Salamangreat card. Then if I have 25 side deck card in my main deck, what is in my side deck? I hear you ask, The answer is simple. If you look a the first paragraph I write. And I didn't mention it yet, so your side deck will full of 15 Orcust cards. But don't worry, we divide extra deck space so you can put both Salamangreat and Orcusts' Extra deck monsters in 1 Extra deck, so you will have much space for your side deck for Orcust. We also give you 3 Pot of extravagance in your deck.
In conclusion:
Don't play this deck in a single game. Play only on the match game.
