Gave this a go. The best cards I could come up with for your (arsenic)free slots are:
Any of the 1 cost CC cards(You don't reliably hit above 3 of a single quanta and even 2 of a single quanta is a little sketchy)
Quake sand(Synergy with the overall theme)
WereWolf(Synergy with darkness :])
Cards without cost that generate quanta.
Or just add Dragons/Eclipses
Cards I tried but never worked well
2xANY card w/ a cost (if you draw both you almost NEVER get them on the field)
Weapons (arsenic/Dagger, both upped and unupped@Dagger) The chance of this just getting destroyed as soon as it is played is so high, that it isn't even worth it.
Sanctuary(Again, 3+Cost card)
Discord(Same as Sanct unfortunately)
Questions:
Should I use the earth on any of the cards? And if so, which? Pests I'm guessing, although I could be wrong.
Would Vampires help this deck at all, or no?
edit: I just proved to myself that it can get 6 wins in Bronze pretty easily. (Guessed that would be true, but wasn't sure) Will try Silver next(really not sure if it can be good here, especially since some bronze matches are close due to not enough damage
edit2: the first game in Silver showed me one thing. I hadn't faced any rush decks in Bronze, but a fire rush deck in silver just destroyed this.
