Golden rabbit has a lot of HP and high attack power. Often it is recommended to use 9S to hack it. I tried other way - by using 2B with counter +5 chip and taunt +6 chip. In this way is used attack power of rabbit and multiplied by 4 which give about 20k damage. if chips used in strategy are taunt +8 and counter +8 it could give even ~60k damage. Even when dealing 20k damage, Rabbit can be defeated in just about 5 min. This strategy is level independent so it can be used at lower levels.
