i agree with this
they have mobility, moves that cover both sides of them, and very destructive kill moves
i say the both sides thing because the likes of falco, marth, sheik, and falcon have more difficulty covering both sides than the aforementioned
Last time I checked both Peach and Puff weren't that mobile. Sure Puff is in the air but she's still slow.
Also what moves of her hits on both sides? Obv apart from dsmash which isn't really useful most of the time.
Only things Puff can do in 1v2 is plank or try to wall if she's not in the middle.
How come fox hits on both sides while Falco doesn't? Fox is **** in 1v2 because he's fast and doesn't have much lag. Plus shine is a Good gtfo move and can kill at low %.
Imo Sheik is very good in 1v2. 2nd best after Fox. She is fast with little lag on her aerials can wall and keep both away with fair/bair + follow up fast with fair to get kills. She's definitly better at covering both sides (fair/bair + dsmash) than Puff
Overall Fox, Puff, Sheik and Peach are the best Team characters. (no order)
Falcon is also pretty good because of his speed and knee.
Tbh I do think Falco is damn good too. He just has to play totally different and more safe.
Lasers are great to interupt your opponents if they are about to kill/combo your teammate + they can safe (shine is also good for helping to recover)
Edit: best Teams imo Fox/Puff Fox/Peach Fox/Sheik Sheik/Puff Sheik/Peach
Also Fox or Sheik/Falcon and Fox/Falco
