I just ran into your arena deck, I'm guessing its pretty similar to the deck up there so I'll share some criticism based on experience and looking at that. I'm by no means a master deck builder so take everything I say with a pinch of salt and ignore me if someone smarter says I'm wrong.
Firstly, I would include more cats. Unless you get the cat + soul catcher combo, you're going nowhere. BLs are a nice touch but not a scratch on cats for producing

quanta. Just 2 cats and two catchers can get you a dragon out each turn, as well as buffing condors and bone walls. The same amount of BLs gets you that for one turn only, kinda sucky compared.
Secondly, consider the mulligan. For those who don't know, the mulligan is a segment of code that redraws your opening hand if you don't have a 0 cost card in it. Since BLs are free to play, they're likely to fill up your hand instead of soul catchers. This happened when I played your arena deck, all I got was cats, sparks and the occasional chaos power. In 12 turns, it drew no Soul catchers, which meant no

creatures, poison or anything. Your deck was on 3-0 when I got it so I'm guessing the other times it did good. Maybe less BLs if you still want to keep some in.
Third, how useful are the chaos powers? Once you have a cat going, you'll be using all your

quanta up so you won't have any spare for powers. Maybe if you don't have a cat its useful, but I think it would be better to focus on having cats than preparing for not having them, if you get me.
The only Schrodinger's cat deck I've ever built properly was for a weekly tournament and it looked like this.

The restriction was it had to cost more than 70

to play and have less than 10 quanta producing cards. This deck did pretty well if I remember correctly and only lost to getting all my catchers stolen. I accidentally started a game in Gold arena with this an won with 83HP left. I believe it was a gravy deck with armagios but it was a while back. So this deck really kicked ass despite restrictions.
Anyway, that's all I've got. Take it or leave it. Hope I helped somewhat.
