Aikido: Throws and Joint Locks and Lifts.
A lift can be used as throwing an opponent if the opponent is not smart and doesn't grip, there is a flaw in your logic.
Daxx keeps it fair and doesn't lift for an expended period of time in his matches.
Also if you can't stop someone from lifting, shoveling, or whatever, then your not all that good.
When Gr3y tested me he shoveled me many times to see if I can stop it.
