How exactly do you break air exchanges?
If by break, you mean Team Aerial Counter, all you have to do is predict which way your opponent is going to hit you during their team aerial combo and hit the same direction and special.
For example: Say your opponent does Towards(In relation to their character) + Special, you would also hit Away(In relation to your character) + Special.
Left and Right count as the same input, giving you up, down, or sideways as your options to counter. 1 in 3 chance if you’re random guessing more if you can guess their intent (meter loss, meter gain, or damage)
You could also just mash that shit out if you think he’s going to do it.
