It's overwhelming at first but it's entirely rewarding once you get past that entry barrier. It's actually one of the most rewarding games you can play.
Quick steps.
1. Pick the character that fits your style. If you don't know, I recommend Anna. She don't require heavy execution but can be extremely deadly. A lot of beginners pick Alisa, though.
2. Go to practice. Go through the whole command list and perform each move, one move at a time. Memorize what you can. I understand each character has 100 to 170+ moves each. You can't be lazy.
3. Start with launchers (anything that launches the opponent into mid-air) and low moves that can lead to combos. This is where you experiment. You have memorized a lot of moves on the command list. Find the filler content for each launcher. Experiment with moves. Be creative. Then, you want to make sure you have learned all of the "bound" moves for your character. Each character has a good assortment of them. These moves are used mid-combo to put the opponent in a bound state on the ground. On the command list, they are indicated with a light green colored box icon. Any moves with a green box icon can be used on your opponent in mid-air to take them into a bound state. Following the bound move, you want to do a combo ender. Again, experiment with the command list you are provided.
If you are too lazy for this process, just youtube combo videos for whichever character you are using.
4. Learn strategies for getting up properly. Again, I've linked
this video so many times now. If you end up being assaulted with juggles non-stop, it's entirely your own fault for not having learned the proper mechanics.
5. Learn spacing.
Sidestepping, movement, it's all very crucial. Don't go running to the opponent. Be calm and patient. Sidestep often. Wait for the opponent to attack. PUNISH!
6. Guarding. So many beginners I've seen that literally let themselves get launched over and over. Don't let that be you. If you can't guard lows, backdash often and create space. Most launchers are punishable. If your opponent does a launcher, PUNISH!
If you don't know what to punish with yet, just press square, then triangle to do two quick jabs.
And you don't want to find yourself in
this situation. A lot of beginners will mash or try different attacks in these scenarios. Just freaking stand there and block.
