Now this would be something I could get behind. Having a pulling mechanic similar to the Fludd (except inverted) instead of a glorified grab.Doesn't have to be that way. Could be a long distance pull. Think like the inverse of the pushing effect of G&W's up aerial. It could work as a gap closer for ranged characters, or a surprise reversal for edge-guarders.
Thus far all the vacuum effects we have seen thus far are not really vacuum effects at all, in the gameplay sense, and more like command grabs. You are either unaffected, or suddenly sucked in at a close range... where as there is potential for something that pulls you in with increased effect with greater proximity.
