Rush Warrior Duels 12-0 three times in one day

So i crafted myself the rush warrior standard deck and when i went into duels wanted to try this out because the value is crazy (Insert HandPala joke) 

But the first time i tried it i got, 12-0, the second time 7-3, and the third time 12-0 

Now the thing is this deck is going to carry you trough the first 3 matches easily, i’ve played 10 or something duels with this and i can’t get anything lower than 7-3, because at the start it is strong as it is, high value = you win when it’s only 16 cards or so

What’s important is the passives you pick:

BEST S+ CLASS: Double Legendaries, you have so many of them which are based on playing rush minnions or just buffing your hand, and you’re gonna get more from card picks and discover spells always.

S Class : Just go for whatever has rush in it, those are the best since the deck is a rush-based deck.

A: Whatever fits your playstile if you didn’t get any of the ones from S or S+

B:The rest are shit im going to be honest, The first time i went 7-3 i just got the worst passvies which didn’t help my deck, 2 choiches 6 options and still nothing

C:Battelcry Passive reduction because that shit wacks and everyone thinks its gonna get them 12-0. Not on me with mah double legendaries hoe
