Well.
Ftilt: I get grabbed using this, and I just about never use it (on purpose, lol). Don't us this, unless you suddenly realize you can get only the last hit in.
Dtilt: A good move to tell the opponent to **** off. I like using it because of its range, and usually, the opponent doesn't suspect you using it. At least from my experience.
AAA: Don't use this unless the opponent WILL get hit by the first attack. If so, he will grab you if you go through with all three hits because of the cool down/lag. It's good to use when you see openings. It often saves me (I don't end up using it a lot because I'm an idiot).
Up Tilt: Use this only for comboing at lower percents. Virtually useless after thirty damage.
So, a game without bair (or in addition to). The problem with bair against people that aren't stupid is that it will end up revealing itself as choreographed. Generally, never use fsmash unless punishing.
To come up with a better game you'll need an objective. Wolf is good at juggling. Why not juggle? Use whatever combos you can to rack up damage, including AAA and bair. I would actually stay away from fair to utilt unless you know you can get it, otherwise you're screwed. Once you have that up, start the juggling process with uair, and if the opponent is good at stopping that, reflector. If they dodge, wait for the end of their invincibility frames and attack.
Sharpen your precision/accuracy and handle of Wolf as well (basically, aside from improving specific things, try and become better in general, such as prediction and accuracy).
I'm sorely disappointed in the fact Wolf didn't do well in Apex, but I'm sure you'll do well. Just go to more tourneys. Other than this, I don't know what to say. God knows I don't have enough experience to make any good judgments.
Note, SH nair is a nice "get the **** out" move for me. Any other random tips I can give you is blaster to dair is unexpected. I'm a high risk player though, reason I wouldn't place high at a tourney. But saying, blaster to dair can work. Wouldn't do it unless you knew you had the chance though.
