Posting to encourage the use of EX DB2 as a punisher.
Since you can buffer specials on this game, this guarantees a punish vs harder to punish moves, or moves that are only like -9, -10, -11, etc. You'll never fall victim to blockstun either.
Alien needs meter to do good damage anyways, unless you land and confirm a clean B11U4, so this is pretty useful when trying to punish Kenjutsu's overhead, Possessed's EX lift, Sub Zero's EX frost bomb, Jason's choke, etc. This method also option selects any variation of Kotal's B1 string, besides a plain B1 stagger and B122 xx overhead.
