A move with with you can shatter structures into small chunks .And throw these at your friends .

Concept:

Breaking a structure into multiple pieces .All pieces will automatically receive some forward inertia with can be amplified with a straight or otherwise modified. The size and number of the fragments would depend on the structure but they really should be bigger than a disc and they should also break and dispawn when making contact with the floor or other structures to not clutter up the Arena.

An alternative version of this would be to make it a status effect like explode .So it only releases the shrapnel when being destroyed.

Pose:

The Left Hand in the straight position and the right in a palm strike .With the palm of your hand facing forward .

Gameplay:

Having a move like this would be great at close range having a shotgun like effect and also very entertaining way of blocking and throwing back objects.
