there are so many styles and options for neutral game that its hard to sit down and list them. i guess here are a few bread and butter options that come to mind:

spear: if you opp is playing floaty you can fish for raw dlights. if you connect sair or recovery is true. you can also throw out dash nairs if your op is floating above single jump height. generally slight on spear is a trap in neutral because its so easy to punish. if grounded, like against sword, spear can out range with nlights.

orb: anytime you can catch an slight into sair or dlight, go for it. other mix ups include a dash dlight that will jump things like bow, gs, gaunt, hammer, blaster dlight. if stacked nlight into chase dodge nlight hits more often than you would think. and of course, abuse raising dair into falling sair to cover your landing.

scythe: so many options. approach weapons that struggle with diagonals like blasters and sword with falling dairs. cover whiffed dlight attempts with the most busted attack in the kit, nlight. scythe can play super floaty or quick and inside on the ground or a bit rangier with dlight. if youre not using strong slight CD nlight or reverse nlight then you should start. its a 50/50 string starter if you time it correctly.

the more you play the more you can steal from other players along the way. weapon throws go hard if youre willing to be a dirtbag ;)
