So in an attempt to actually stay ON topic here, I'll just discuss my thoughts on the entrants here anyway.
#1: Very Leech-like, and it seems pretty lethal as well. I also like how it fits a Halloween theme, sorta.
#2: Seen this before. Not too surprising that it's too effective since it uses some pretty OP weapons.
#3: Is this meant to knock on IRL tournament hosts who allow shell spinners with lots of weapons? That's the vibe it gave me anyway.
#4: This looks tough as nails and the wedges look rather deadly well. Not much else to say otherwise, as it gets the job done.
