Okay, I know there are many threads out there that explain some things and have been discussed but I just feel like putting it in one 
So I’ve been seeing these “Does Strider need doom”…IMO, yes if you are in a tournament or want to win. If you are good, then, you wwould probably switch to a more advanced trap, say spiral or sentinel. Doom will does the most blocking chip though
** Using Strider **
As we all know, you try to keep your opponent trapped for as long as possible, timing the doom assist closest to the opponent for some chip. Of course, nothing is easy. Starting the matchup, you can either:
1) do a c.lk+assist c.mk…
2) do a j.lk+assist j.mk, j.hp, j.hk
or ** 3) ** just block and assist
** Note that strider’s c.lp is the quickest startup, should be used against other mags and striders. **
So when you do trap, you’d want to pressure using birds, panthers and your doom assist.
** Trapping Cable **
It may not look like it, because most people think that S/D is “the anti-scrub”, but a good cable knows what he is doing.
Against cable, you wouldnt wanna necessarily “trap” most of the game. A pantherxxorbs would leave you open for an AHVB. Invincible assists (meaning cammy and ken) would be a major problem. Cable will most of the time fade (jump) back and wait for your assist or for that AHVB. What you want to do is annoy cable. To do that, you just simply teleport near him. When you are close, assist and teleport the other way, so he is facing strider and away from the assist. Do that for the rest of the game, and you should be safe. Blocking is the key to beating cable. I know I have not yet said anything about the orbs, but, you only want to do that if your opponent is in blockstun. Dont try it from afar. If, somehow, you are feeling cocky and want to do so, throw a bird with a bomb to it (back, charge foward+hk).
** Trapping Sentinel **
This will really tick you off. Dont try anything on the startup, sentinel’s j. lp beats out all of strider’s moves. Wait for the pause, and teleport on him. You mostly want to use the birds, because sentinel is so big, a standing one will hit a bird from afar. Panthers are used after the trap to buy time. Remember, after the 3 bird, or panther, you can xxorbs. Once sentinel is trapped, he cannot do much. Yet its still hard to do that. Teleport without orbs, and when doom’s assists hits, panther xxorbs.
** Trapping Storm **
This, without doubt, is your hardest opponent. With only S/D, its almost impossible to bring her down quickly. Dont waste your supers while she is in the air. Wait for your doom assist to hit. Just get close, and place the assist on where she is landing. Then, trap her. Use the basic; magic(on ground) and on the hk, + assist. Then, panther, panther, birdxxorbs.
** Trapping Magneto **
This is your easiest opponent out of the 4 gods. Magneto cannot stay in the air as long as storm, but he can still buy time and run away. So play strider like you would against a mix of cable, sentinel, and storm. There is no serious threat that mag can do, although psylocke beats doom, thats all you have to watch out for. If you are smart and careful, this shouldn’t be a big problem for you.
Good luck to all the strider users out there :tup:
