I apologize if this post belongs more to the custom move thread but because the flow of conversation is currently on custom moves, I figured I post here.
Recently played a few friendly matches against a friend with a custom Marth of dashing assault, crescent slash, and iai counter. The fthrow to CS does seem awfully consistently, even at higher percent. I'm not sure if my friend was di-ing improperly but it seemed that I can adjust to the di just with a dash forward or jump than using cs. If nothing else, you can probably at least use the threat of CS as a way to bait airdodges at higher percents.
CS also forces the opponent to be a bit more weary when edgeguarding near the ledge since the hitbox of CS hit way below the stage. Also, thanks to the weaving you can do after the move, you can do the occasional cute gimmicks when hanging on the ledge like drop then CS to shark edgeguarding opponents and go back to the ledge quickly or drop, jump, and CS to a platform on stages like battlefield.
Just throwing the move as an antiair and edgeguard onstage against an opponent recovering high may also be viable. If I recall @

's frame data on custom moves correctly, CS has full invincibility as it is rising. So theoretically at least, if a character like Mario is shooting projectiles as they're falling onto the stage, you can use CS to punish them.
Traditionally, it is said that the problem with Marth since melee is that he either kills early or really late outside of edgeguarding situations. CS may provide us with a consistent kill move and set-up, which would address that age old problem. For this reason and several others, I think this move is great but I would love to hear others' opinions and thoughts on the matter. The last thing I want is to mislead myself into thinking this move is amazing if its not.
