btw, you can actually frametrap people into your pkt2 to kill them in this game if they're near the ground, without just being flashy
in some situations, you just pkt1 towards them, they either get hit or airdodge
if they airdodge and land with it, they're trapped in the lag, so you just hit them with pkt2 (if you're close enough, then with the impact-sweetspot).
This generally works better (regardless of which hitbox will hit them) , if you're close to them, since it won't take as long to get the pkt2
also this generally works better the closer you are to the egde, since they can't just back away, and if they do, they give you stage control
if they hit the pkt1 with an aerial (or another hitbox in the air), then you can grab them when they land and punish them
i actually got '(side-b) -> dthrow -> fair -> fair -> uair -> pkt2 kill' as a 0 to death combo on quite some people already, (depends on which character they play for the uair to connect and if you started the combo with pk-fire)
both of you are actually in the perfect position after you landed after the uair for the pkt2 to work, you're on the ground or near it, both near the edge and they got the right height
and even if you just hit them with pkt1 or get the grab near the ledge, you did a lot of damage and got stage control
Ness is great at keeping stage control and momentum in your favor
