Gonna throw out some Alex notes here:
- use meter for EX, unless you get a juicy opportunity for super damage
- EX elbow charge is fast and can punish a lot of stuff
- d.fp is a decent anti-air and it hits twice, but if it hits once you can combo afterwards (I'd suggest his dp kick move as it causes a knockdown)
- standing fierce is his overhead. Use it on wakeup. When they get scared of it, time to command throw. If they start parrying it, start using the b-fierce headbutt move (and of course if they start reversal/super on wakeup, start blocking).
- forward fierce seems like an awesome anti-air, but if they parry it they get a fat combo so be wary
- use stomps sparingly, they are really good as it is an overhead, but again, good players can parry it on reaction
- use his punch command throw (power bomb) and not his kick command throw (ddt)
- Bread and butter combo - jump fierce -> standing medium kick -> jab flash punch. Does crazy damage, and you can make it even more damaging (and causes a knockdown) by EXing the flash punch. You should get this combo down, it isn't hard.
- fierce flash punch leads to crazy damage, but really slow. Use only for punishment situations.
EDIT:
His elbow charge is hold back for two seconds, forward and kick. His stomps are charge down then up and kick.
