Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Hey TSRD, would you allow Vacuum Wave + Confusion, Vacuum Wave + False Swipe, Vacuum Wave + Rock Smash or Vacuum Wave + Power Up Punch, please let me know. Thanks.
Generally I ask that you explain how a combination is supposed to work. Still I would say maybe yes on Vacuum Wave+Confusion and probably no on the other three.
Hey TSRD, the Drill Run by Joey on Kurage is SE as you marked in the calcs, but the result is not multipled. Please correct 'em. I am ordering any way. Also thanks for reffing it so quickly. You are amazing ^_^
