Sikseven~~~67

How to make a training bot with 67 HP: Pick Jin. Use your super (Hatchling's Call) to drag 2 bots. Hit the bot you want to make with 67 HP with a normal attack (2000 damage), then get super close and hit it 4 times with Gadget 2 (1600 damage). Finally, hit it with a long-range attack (333 damage) and you're done!
