Well I made it a point to say that is was cool, but my point is that it isn't anything more than a bait. If they are blocking and not bad they will never be hit by it (its either a high immediately after a multi hit high or the opponent is still in the air, there really isn't a reason to mess up defensively), so it will only catch them if they are going for a reversal, and I personally prefer not using 2 meters
In a majority of situations. Rather than os a counter super, you can just block for 10 frames and then go for a tricky reset or simple low/throw mix up. If they mash out super/invincible reversals you will be blocking it, and its probably unsafe so you get a ch anyway. Blockig as a bait is equally as safe and less costly. Also more consistant because you may have no vial or a non damage vial.
