It's amazing that there's such a great Palutena guide this early in the game. One small gripe tho, it seems that this guide kinda neglects the more passive playstyle that Palutena can have. You talk about Autoreticle to interrupt charges, but less to bully from far away. You talk about Explosive Flame for punishing approaches at high percents, but stuff like the further variant of Explosive Flame in neutral can also force approaches at low %s, as combos like Explosive Flame to Autoreticle do ungodly amounts of damage from faraway. You should also add how dashing in with Explosive Flame, or using it in juggle situations are great ways to use this move. But then again, I'm not the best Palutena main, so maybe Explosive Flame does suck. So yeah, adding a section differentiating between this more aggressive playstyle that this guide emphasizes (seen in Palutenas like Nairo's) vs the more campy playstyle (seen in Palutenas like Dabuz's), along with considering moves like Autoreticle and Explosive Flame in context of that playstyle would definitely make this a 5 star guide. Also, maybe add that she can have trouble killing at high percents, as she has to sometimes commit hard to get that kill. Another piece of advice, you should mention that when you go offstage, try and face towards the stage, as not only is back air usually better than forward air at edgeguarding, but down air lands more reliably to the side of you when use the back hitbox.
Sidenote: When I provide examples of Palutena's campier playstyle, I don't mean that all you should do as her is play that way, because other characters can play the camp game much better. I just mean that alternating between her campy playstyle when you're in the lead to her more aggressive playstyle when you feel like you need to push your advantage can be another strategy she can use.
