A custom mode that is exactly the same as Ladder SC2, but every APM removes a set amount of minerals. And each player has a mineral bank account that can dip into negative. So the faster you click the more you go into bankruptcy. For sake of example every APM is -5 minerals. Is this possible to make in the SC2 galaxy editor?
The potential problem I see with this custom mod would be players would be 4 Gating in their respective races blindly with as little APM as possible, and then just microing the 12 units made or what have you. But if that were the meta than perhaps someone could prepare an anti build with very few clicks.
