my First idea for a new tower.
After a couple of waves the game starts getting interesting. But all u need is luck!
Without luck u don't get the needed towers, gears and portions. But what u have is gold... Many gold.
Gold at early game is rare couse u have to safe it for ur rare carry. At midgame it's needet to support the carry. After wave 150 gold is only needet to boost satellite.
So there is a point in every game where gold becomes useless.
There should be more options to use money, to get it and to waste it.
My idea is to get a blackmarket card.
Range, dmg, speed... Irrelevant.
We need two abilities.
First - Market
U can sell and buy towers, gear and portions.
Second - Experience
The higher the level of the market, the better should be the cards u can buy (except of uniques).
I don't know about balancing but should be as important as transmuting.
Try ur risk with transmute at lower costs or get what u need with higher cost. (or even get material for transmute)
I guess you've given a good idea indeed. Its really interesting. I support your idea
Could be a bit overpowered...but to make it more balanced have it cost cumilitive for each card you buy, and the card is random.
So like you want a yellow rare card. First try is 1000, 2nd is 2000, 3rd is 4000 etc..or if thats to much then increase it by 1.25% or something each time
