Alright now time for a lengthy and detailed reply/2nd post. This one will be flooded with alot of info, so be forewarned. I'll focus on Astaroth because I feel I can best explain him to you, being an Astaroth tournament player myself. I'll try and use the video I linked for an easy reference and cite other references while I go over it!
One of the few was that Saitoh just about took every opportunity he found to attack Keev. Those air grabs looked complex. They also didnt just rush in recklessly, like I always did. And they were taking advantage on their positions near the edges of the ring or anywhere on the ring. Final thing i noticed was that Saitoh shortened his unblockables, which made me learn that Unblockables dont have to be fully charged to be efficient.
Astaroth lives and dies on how well he can make an opponent afraid of him/his options. His basic mix-up at close range is Bullrush (66K), delayed Bullrush (pause slightly before doing 66K) to catch people flinch ducking in fear of a throw and to catch people who sidestep because the waiting re-aligns him to his opponent, or Command Throw A or B (63214 A+G or 63214 B+G). Saitoh also makes use of 3(B) slight hold to see how Keev will react because if Keev stops guarding and goes to sidestep it, it can catch him and give him the 2A+K ground pickup combo that you saw there. Why are each of these moves good? Allow me to explain.
Bullrush (66K) is a mid hitting, tech crouch, body attack that knocks down and rings out at ring edges, and wall-splats near walls. Also, its very fast for Astaroth.
What does all this mean? Well, mid means it hit's opponents who crouch and opponents who stand have to block it. Tech-crouch means it ducks under high attacks and throws during the move animation. It being a Body Attack is relevant against certain auto-impacts and defenses which don't defend against that type of attack. Knockdown is important because it allows Astaroth to run up and continue pressuring. Ring Out and Wall Splat are obvious, of course. On top of these things the move is "safe" against most characters, meaning if they block it; they do not get any "free" hits on Astaroth before he can guard again.
63214A+G is the command throw you will see hit with Astaroth most often. The throw does great damage, and leaves the opponent at his feet afterwords. On top of that, because it's a command throw the window for the opponent to break the throw is smaller. Also, it has the benefit of not being able to Guard Impacted or Parried.
As another bonus, if the opponent is jumping while you do this throw, it will shift into an air-throw, so this throw unlike all others can be used to punish people jumping to avoid throws.
63214B+G is the reason the above throw hits so much. This throw combos into both 22B and 28B+G (also known as Titan Bomb), and does about 50% life in damage. It also has amazing Ring-Out potential in any direction by just Bullrushing or A+G throwing them out of the air after. This throw is so scary, people often ONLY break B instead of A, thus giving you lots of free A throws.
Ok, back on the subject of delayed unblockables. 4(A+B) can also be used in a similar fashion as a slightly delayed unblockable but is riskier. Whereas if he does 3(B)and stops short and it get's blocked, Astaroth is safer from taking free hits because of 3(B)'s push-back and quick recovery. 4(A+B) is good because on a counter-hit or catching someone moving, it gives a stun which gives Astaroth damage and position. The downside is, it's riskier because if you stop short and the move is blocked; Astaroth is heavily punishable. He's at what we call "-20". This is short for -20 frames, which is the speed the game is measured in.
A quick rundown on frames: The game runs at 60 frames per second. Moves in the game have frames to activate relative to their speed, and recovery frames on block. Let's say an Asta was facing another Asta. Asta1 does 4(A+B)
and Asta2 blocks it. Asta1 is considered to be at -20, so if Asta2 does any move 20 frames or under, its guaranteed to hit because Asta1 cannot block. This is called "Block Punishment" or just "Punishment". Asta2 can get a "free" Bullrush because it executes in 17 frames or "i17" (the i is short for instant).

Thank You For The Info! ;] It really taught me something, (Unless im wrong on something, correct me please if i am)
Ill probably use some Practice Mode tonite. But just one question: Out of my 3 Selections of chars id like to know better and master, which one would be more user friendly to me at the knowledge/skill level of SC im at? Astaroth, Nightmare or Sophie?
Your welcome for the info, I hope it gives you a good start! I would suggest leaning towards Astaroth because in a wierd way he teaches you the basics of the game better than any other character. Spacing, Throwing, Attack Timing, and using your opportunities. If you have any more questions, feel free to ask. I could analyze that Saitoh vs Keev video ALL DAY for many posts, there is so much good stuff in it.
