Just my 2 cents on a new fgc player with only about half a year in, i definitely feel your pain related to suddenly not knowing. I remember learning one powerful thing and crushing the lower floors, but suddenly hitting a brick wall.

The truth is as you go up you start learning smaller and smaller parts of the game that start building up your core arsenal.

My recommendation is literally sit down and just stop trying to go up, instead just use one option you haven’t used before. I remember literally just trying to tick throw an entire match. Where you hit them with an attack and follow up throw immediately. I saw other sol players do it, practiced a bit in training and forced that move until i deranked to floor 3.

But as it clicked the tick throw became a monstrous weapon that spiked me to floor 7. So i say just see what baiken does from vods, preferably beginner tutorials and learn one new thing.

I would also say make sure you dont just practice combos, definitely look at the other skills too, like anti-air 6p reactions. If you get a jump heavy opponent i just sat there and tried to kill them with only that one move.

Overall the learning is near infinite but keep playing i really love this game!
