Even so, the properties of the fog don't seem very consistent. I tried pushing the opponent to the corner and throwing him, then unleashing an EX fog. When I did a 5b after he wakes up, sometimes he air techs, sometimes he lands on the ground and ground techs, sometimes he doesn't air tech immediately but air techs when he's slightly lower in the air. Almost as if there's a certain period when the fog will have a no-airtech property and if the opponent's in the air out of that period of time, he can airtech.
