I thought of some cool badge ideas that I'd definitely like to see in game. Here are some:
1. Ready for War: hold one hundred or more unique blades (This should definitely be a badge, I would love to have this and I can think of some unique ways to accomplish it)
2. On the brink of death: win a match with only one health.
3. Unlucky: Get hurt by your own Insane Bolt 3 times in a row
