The cancel? The cancel is only really punishable on a read. Because you have to be blocking in case they do an actual teleport. BUT, there’s some tactics you can use, but are risky. Such as jumping backwards and doing a jumping 2 on the way down. It’s not super reliable but an option, this is tech dating back to UMK3. Like I said it doesn’t cover all options and distances but it works more than you’d think.
Best option other than that is to block and try to react to the mixup after the teleport cancel. Try to Tech the throw or crouch. It’s more of a read type of move for the cancel. But if they go for the teleport you can punish very consistently (if you’re blocking of course) if you practice it, regardless of they amplify or not.
