Yes, I use crescendo often.
First of all, you can use H version as some short of DP. It has some invincibility, it’s very unsafe, and covers only vertically, so don’t get very happy using it. It’s good for jump cross ups attempts.
You can play footsies while hovering. Jump, hover near the rival but not at anti-air range. Use M kick, a very long range attack that pushes you back. Sometimes cover yourself with the bass assist. If they jump, use L version of crescendo.
When they learn to respect your space, call bass assist, jump, hover, advance, your assist hits your rival/he blocks the assist, you reach his position, and then you have a left-right mix up, and you can use here H crescendo as opener.
Finally, you can bait anti-airs with a jump, hover back to avoid them, and punish with M crescendo
EDIT: @Infilament just replied you here , he can give you better advice than me
