I have no problem whatsoever with shovels. I can usually beat them. If someone tries too shovel you and both your hands are held to their hands, extend both pecs, elbows, contract both wrists and raise both shoulders. Usually works. Depends on the situation.

I recommend making a bigger dojo, so players will actually try to wrestle each other to the ground rather than shovelling cause you won't go outside the dojo when you get shovelled with a bigger dojo.
