I'm not too sure about this one personally. It seems like it would be reliant on an ability which prevents voltturning or through another slow voltturner (of which we already have Rotom-W, defensive Landorus-T, Scizor, Pangoro and Lagging Tail Whimsicott - just listing the most notable ones). It seems like it is very limited in the ways that it could be implemented. While I agree that VoltTurning is a big, I feel like a Pokemon that completely shuts down a number of playstyles (HO VoltTurn, Defensive VoltTurn, Balanced VoltTurn and any other VoltTurn playstyle you can think of) would become limiting towards teambuilding. I'm not going to reject it for now because I want to see more discussion, but keep it in mind that I may. I'll give it to you that it would be a very influential niche tho, which is part of the aim of CAP, which is the main reason why I'm not rejecting it right away (and one which has failed with a lot of Smogon's CAPs, with them sitting to rot - unused in CAP OU)
