it looks like a solid deck so far. maybe you can ad 1-2 aether pillar. replace a fire pillar or a deflag if you want to stay on 30 cards.
... It worked good but not great. ...
fractal decks are always slow (if you compare with other rush decks), because you have to wait untill you have build up that aether quanta.
upgraded aether pillars will speed this up.
im not sure how this work on t50. rol decks, shield heavy decks, nasty rushs, discords, could cause some problems there.
but if you ad a bit defense (SoG or dim. shield), you could go for lvl 5 with a upgraded version.
