The main deck I used was Bonebolt.

Bonebolt has synergy between Bone Wall and Thunderbolt - it isn't just as bunch of overpowered cards thrown together. Well, actually, it's both. ^_^
Arsenic is decent in a rush, but super strong in a defensive deck because the poison just keeps building every turn. And Poison is pretty cool because it can't be stopped by shields or CC. Thunderbolt can kill most creatures in the game for almost no quanta, and Bone Wall easily stops its fair share of damage. The Dragons are thrown in for when you have extra quanta, and they actually saved me in the finals. I was down to 17 health with no Bone Wall and not enough poison damage, while he had a Sky Dragon and Owl's Eye ready to murder me. Oh, and a hax shield, but RNG won me the game and possibly won me the tourney. Sorry MegroN. Anyways, pic below.
I used a few other decks to get me my wins against my other opponents. I used Mono Death in my first match because Bonebolt would've lost to deuce's Flying Titans (that deck was terrifying). Against Rutarete I built a really weird and specific counterdeck involving Lobotomizers, Bone Walls, and a bad quanta distribution. It worked, somehow.
Ty to Sub for hosting - not just this one, but many of the ones I've entered lately. It's great to have you.
