I'm gonna say no to this.
Why add new elements when you can just increase the existing card pool?
New elements at this point and stage will just unbalance the game.
it most likely will, but it would also be cool to see more elements, and it will only imbalance it for like a couple of months, and then everything will be fine-tuned again
I seriously doubt that. There is a whole lot of work in bring in just one new element. First, you need the cards, at least 10. And there is no telling what those card would be, so it could heavily unbalance the game. Then you have to make the elements interface different to make room for the quanta pool, and the Element name in the beginning. You'd have to make room for it in the bizarre too.
But that also requires coding all the new mechanics of the card, and include new cards in already used mechanics such as Mutation and Hatch.
Then it adds the added depth of brand new strategies, and a ton of them at that. All in all, it would be a huge change, it could possibly even make the game worse.
