A relatively straightforward Chemicritter deck revolving around getting Catalyst Field out to begin your science experiment (popping one card per turn). Gemini Ablation summons Geminis from the deck with their effects. Carbo Crab is the main set up to get a Gemini in the graveyard and then one into your hand. Oxy Ox summons a monster from the hand and adjusts the level to allow for either Rank 2 or 8 XYZ such as Dingirsu, Cursed Javelin, Toadally Awesome, and Methydraco. First of the Dragons w/ Dragon Mirror helps get some minor protection. Titanocider & Lost Wind I personally use to shut down extra deck monsters or at least slow them down. Burnout is a good way to set up your rank plays and Starving Venom I've never used but it does help get rid of pesky monsters when combined with Super Poly since Dark is pretty common. I also took the liberty of adding in a couple more Predaplants and Invoked Elesium. Plus, Super Poly fits with the chemistry theme.
Reduce, reuse, recycle! And like with any good chemistry experiment: blow things up! This was a fun deck to build and playtest. Enjoy!
PS, yes I like to run more than 40 cards :)
