I read that you can land Alex's fully charged v-trigger off a crush counter sweep cancelled into his v-trigger. I haven't tried it myself, but that sounds like something super powerful against non-reversal characters.
Ok, I've tested this out and it works, but the timing is super tough.
If you time it perfectly, reversals will pass through you. However, charge too late and it will hit you. Charge too early, and the game will autocorrect the reversal and hit you. But there is a perfect timing where it will both hit the player on wakeup if they do nothing/block/spam jab, and go through invulnerable moves if they try to reversal.
I tried to CC sweep xx v-trigger, tap s.lp or c.lp then immediately charge clothesline, but it wasn't "perfect". It was almost perfect, and will catch jumpers or non-invulnerable moves, but I'd still get hit by the reversal. Also, clothesline has a lot of recovery, so you don't really get to punish the whiffed reversal unless it was a super.
Still, pretty powerful.
