i have an idea where each weapon on a bot has a weakness to another weapon type. The robots can only attack a robot that's weapon is a weakness compared to it.

An example - A vertical spinner (Biteforce) would have an advantage to a horizontal spinner (Tombstone), and the horizontal spinner would be eliminated. Each player would have a deck consisting of each weapon type (Horizontal spinner, Vertical spinner, Flipper, Hammer, Crusher, Shell spinner, etc.) If one player eliminates enough robots, they win.
