Zero starts the round, gets a hit, goes through the motions and either lightning loops you to death or uses the "unblockable tac" to switch to Magneto. Magneto starts doing his thing until the opposition starts gaining meter. They drop the infinite and reset the situation (depending on the assists, his resets get really ridiculous). Say you survive, and land back on the ground. Your screwed yourself, since you're going to have to block. If he has drones, pushblocking won't help you. If he continues with the infinite, then you get resources, but you're going to have to guess which side you're coming in on. Get, then die via XF Gravity squeeze or DHC to Zero. Of course, he can just raw tag back to Zero and force you to block lightning.
