Wait, going through your post showed me I didn't make a mistake at all. So the guaranteed PKT2 combo you're touting isn't Praying? Then ignore praying. You, however, talked a lot as if the opponent didn't have familiarity with the matchup.
And here's what you said:
PKT2 is not reliable at all. It's highly situational to combo into, it's friggin' slow if you don't combo into it and on whiff, you're wide open).
And here's what you said:
Experienced players will know when to shield and when not.And that's not even counting the psychological consequences of being hit by it once, such as a tendency to shield too much when pk thunder is being used (a tendency that is easily exploited).
Or not. Or the opponent to could know how to fight Ness and how to not get hit into PKT2. And they could know when one should jump off the stage to edgeguard Ness and how to do it (yes, not all characters can do this, but you don't do it with characters which cannot).An overzealous opponent will often find himself falling into the tail (which means it's over) and if you've landed pk thunder 2 before being hit off the stage (which is fairly likely) then the opponent often hesitates to jump off after you in the first place. Of course, you don't need to rely on this because Ness can recover from a wide variety of angles (with the proper precision) and his aerials offer plenty of protection; however, the hesitation is nevertheless a phenomenon you will observe.
