Discussion about real decks is fun and all but i want to see just how messed up, impractical or weird a deck can get. I'll go first: 
I call this one "Random Bullshit GO!"
(factorizing a null-stone yields random prime rocks, so this deck is basically just completely random stones every time you play. fun! )
(amber's pickaxe is an unused tool in the game files. i edited one of my cards into a "1777" by editing my save file directly. you can just use 71-stone, really.) Amber's pickaxe is not unused. i completed the entire game for god's sake how did i forget about it. there's like 4 tools in total.
(you can actually set your deck to contain just about any number, but weird things start to happen if you go too high.)
i was also thinking of combining absurdly high negative numbers and 29-stone, but the hand discarding thing prevents you from actually using all that energy.
(also sorry for posting here when the last discussion has been about two months ago. i love reviving old discussions)
