OK, guys here's something you NEED to try out:
Regular phase forward over your opponent during their wakeup
Basic idea is to phase through your opponents potential wakeup attack and whiff punish. So far I've found only 2 wakeup attacks that it doesn't work against(Tempest Ex spin and Sektor Ex Flameburner). Against teleports (Scorpion, Ermac, Sektor, Smoke, Mileena) you will always recover in time to block them. If your opponent chose to delay their wakeup, just go for the 50/50 or whatever you fancy. Also the timing for doing this is very forgiving.
I've had tremendous success doing this the past few days and I hope you will too.
