Strategy
Overview
Cammy is easily one of the strongest characters in CvS2, and is pretty easy as well. Her strengths are obvious, with her incredible best-in-class normals and three powerful specials (and two sorta useless ones) that give her an amazing grounded game. To compliment this, her walkspeed is stellar, allowing her to walk in and out of the opponents range to punish with a fast normal like 2MK or 5HP. The opponent has to be careful jumping as well, as Cammy's Cannon Spike is an incredible anti-air. If the opponent gets caught by one of Cammy's normals on the ground, she can often cancel into HK Spiral Arrow for good damage and a knockdown.
If Cammy can get a knockdown, her aggression is stellar. This is mostly thanks to her absolute best normal, cl.HP. This is a 3 frame normal, tying it in speed with very little besides jabs, and is a massive +10 on block. This allows Cammy to basically do whatever she wants after this, even if it gets blocked. She can even just repeatedly walk up and cl.HP again and again, threatening throw or DP or airthrow at all times. This becomes especially scary the moment she can build enough meter for a level 3 SDS, as a confirm into super gives her phenomenal damage and she has more than enough confirms into SDS.
Cammy's defense is no joke either, sporting plenty of amazing normals for mashing, a DP, a total of 4 throws, and a fast forward moving special to catch them trying to do things like 2MK > Fireball. Cammy is usually played in K or C Groove as well, and JD/Parry makes her very scary as a single one usually leads into a Spiral Arrow or level 3 SDS, turning the game in her favor immediately.
Despite her strengths, Cammy has two major weaknesses. The first and non-Groove specific weakness is her jump. Despite her powerful divekick, Cammy has a very slow jump that goes very high. This makes reacting to her jumps and anti-airing her simple, and makes jumping with her very scary. She also can't reliably punish some things with jump like other characters, but this is usually mitigated by her long reaching limbs. Her other main weakness is that she has one of the worst rolls in the game, if not the absolute worst. Slow and very reactable, Cammy in roll Grooves has to ignore the powerful defensive and neutral mechanic since she will almost always get punished. This hurts her viability in Grooves like A and N quite a lot. These both together means Cammy has to play a more patient neutral. She can't jump or roll in, so she has to get a whiff punish into a knockdown to start her offense. Luckily, she can do this easily while threatening a shockingly fast walk up.
If you can deal with playing around Cammy's weaknesses and playing into her strengths, she's an incredible powerhouse of a top tier. She plays a very simple footsies-style game, and especially in K Groove is a damage machine utilizing the powerful Rage mechanic. Learn your spacings, lab your links, and punish into knockdowns to start winning games with Cammy.
