This is a control-heavy rainbow poison deck.
Starting it up:
Quantum Towers (9) and Supernova (6); it's often very important to get out a scorpion early on; a second- or third-turn Dune Scorpion is fantastic. The earlier you can get out the scorpions, the better.
The Offense:
Arsenic (2) is a fantastic weapon. It deals an incredible amount of damage over the course of a game, and has a whopping cost of... two Death quanta.
Nightstalkers (2) inflict a good amount of poison with each hit, definitely worth buffing up to speed up the poisoning process.
Scorpions (2) are a good balanced card; inflicts one poison, no need for attack buffing.
Puffer Fish (1) needs no support to shine. Its three attack lets it attack through virtually all shields, and has a good amount of health to take some abuse.
Dune Scorpions (2): Neurotoxin is incredibly powerful; even of the Dune Scorpion falls the turn after it is played, a single successful attack is all that is needed for poison to start stacking.
Control:
Improved Steal (2) and Explosion (2) handle stuff like Lobotomizers and shields, when you don't have Momentum.
Thunderbolts (2) are perfect for killing Otyughs that threaten to devour all of my creatures.
Congeal (1) and Rewind (1) are very cheap cards that stall for more time, letting poison wear away at my opponent.
Supporting Cast:
Chaos Power (1) guarantees at least a +1 boost to attack. The boost in health is also welcome. With its tiny cost of a single Entropy quantum, Chaos Power is a great card.
Unstoppable (3) is virtually required in any deck with scorpions. It's fairly self-explanatory.
Improved Blessing (1) uses my spare Light quanta. It's more reliable than Chaos Power, but costs more.
Stayin' Alive:
Shard of Gratitude (4) and Improved Fog (1) are both very cheap considering how much damage they cancel out.
Suggestions are welcome!
