I feel like being productive right now, so I’m opening this thread thread up. This thread is ment to anyone who plays this team and whatever order they put it in. Disscuss tactics, dynamics, and whatever…
Why pick this team?
Theoretically, there is no REAL counter to this team, if you face a Storm/Cable team, you can go Doom/Storm to counter it. Or if your up against a Storm/Sent, then you can also pick Storm/Sent (via button switching). The only problem w/ this team is you only get one chance to surprise your opponent in a tournament. So you have to pick wisely.The element of surprise should give you an edge in the fight. You can start Storm against Magneto or Sentinel, or you can start Doom against those annoying BH’s and Sprials. The reason I don’t put Sentinel first is the lack of that one hit kill… but I also like Sentinel as my clean up character which means when I get my APA xx Hail, then/or Lightning Storm xx HSF. My Sent gets the easy task of turtling and casually chipping away life at the remaining characters.
When to pick Storm/Sent/Doom.
Obviously when you fight Sentinel, your going to want to have Storm in the point possition. Supposedly Storm/Doom is supposed to have a good chance against Sent/CapCom. But if your Doom/Sent is super godlike, then you may take the chance of starting out Doom (although it’s not really reccommended to go up against Sent/CapCom w/o an anti-air). I’m still experimenting on Doom/Sent vs Sent/CapCom, I fought mixup in a recent Gville tournament and surprised him a little bit, but 2nd match he found out what I was doing. 
Also, you may want to start Storm when your fighting Magneto. Doom vs Magneto isn’t as bad as it was a couple years ago. Doom/Sent can get a lot of shit in Magnetos way and pressure him pretty well. As long as Doom keeps the tempo of the match in his favore he’ll be ok.
When to pick Doom/Storm/Sent
This team is the ANTI-Spiral. Doom’s j.fp + drones keep Spiral at bay, and generally annoy her as she tries to get swords. This will turn into levels, and when you get levels you can go rush HER down. Remember one hit and it’s over for Spiral. And if anyway your losing in this match-up get Spiral to teleport some how, then apa xx hail is instant, and catch her while she’s comming out of the teleport.
Another time you should start Doom is against BH. Doom is also the counter to BH. Find out more here.

General Strategies Doom/Storm/Sent
A good way to start out the match is with a j.hk+Sentinel, although it’s a little old, it still catches people off guard because it’s just quick and high in priority. If they block it, you can air dash into a safe zone, and drop a photon. If it hits, and your lucky enough to be low enough to the ground, you can dash in and although roll able you can, OTG them for a combo.
For an opening move, I usually go for df.hk, or j.hk two of Doom’s fastest moves.
A good zoning tactic with Doom/Sent is j.fp+Drones, then see what the other person does.
If they super jump, you can wavedash over to them for a little rushdown game, or throw ground photons to cover space. Which one you do is totally up to you, but some options are better against some other people.
Another good move for Doom/Sent is to j.hk+drones everywhere. This is espeically good since, if you have 2 meters. This means you can automatically fry the opponent if they try anything funny(like typhoon hail out of randomness) and then drones cover the ground while you fly around kicking everwhere. However, this isn’t an abusable tactic if the opponent can get above Doom. Above Doom is the weak point of the j.hk, and the drones won’t be in possition to cover. But this is easily solved by air dashing back.
Something I like to do with Doom/Sent is punish assist. Drones hurt a lot, and when facing someone like Sentinel or Magneto (who abuse their assist WAY too much.) Drones can come in and beat up or soften them up a little bit before getting them w/ APA xx Hail. If you don’t have enough meter for apa xx hail, I’ll usually settle for a standing fierce or kick launcher xx fly back, unfly, or just j.fp will do decent damage. Usually when people see their assist getting beat up, they’ll try to get to you inbetween hits (Like when you kick launch an assist /\ lk, lk a person would try to hit you before you SJ). This is a big mistake on their part, because you can instantly APA xx Hail the assist (and if your lucky enough the point character too) 
I’ll stop here for now. Peace!
