I think some of these "gimmicks" are really effective though.
I'm not gonna go through the whole 2+ hour stream but here's a match the 1st match between Playing2win and Sonicfox on Pig's Twitch. I'm gonna give a time stamp of every time P2W tried to do some of the things you've mentioned.

0:16- Get's hit with an instant air-stomp- Got caught blocking high. No he could not have anti-aired because he was just hit with a d1 and he was negative.
0:18- Ducks an air laser but he doesn't roll in- decides it's better to zone as Deadhot than attempt to 50/50 Darkseid to death.
0:21- Sonic pulls out trait- P2W doesn't react quickly enough to punish, it's not clear if he even CAN punish. Sonic throws minion and does a GROUND teleport. P2W jumps back to avoid the set up and get's caught by Sonic's ji1. That's just an amazing adjustment or read by Sonicfox. It's hard to tell which.
0:27- P2W activates trait. He's negative, Sonic goes for a jump in, P2W doesn't have time to anti-air, decides to block high, get's hit by air stomp again. Yes, he could've blocked it but that was a pure 50/50. It's fair to say he shouldn't have activated trait in that situation.
0:31 P2W sees a jump in, reacts too late to anti-air, eats another stomp because he's pressing buttons instead of blocking low.
0:34 P2W sees AN EMPTY AIR TELEPORT and tries to anti-air with d2 and it completely whiffs because he's in the corner and it crossed up. He eats an air stomp and gets full comboed for his troubles. Sonic sees that d2 is whiffing so he does the same thing 2 more times.
1:10 P2W successfully air-to-airs an empty air teleport from Sonic
1:20- P2W attempts to poke after mb Knee and eats a combo- maybe he thought Sonic was going for a string with his + frames
1:34- P2W dies to lasers.
