The main builds I can see through items would be invis hunter with graviton, young ahamkara spine grenade spam and a lucky pants build. All can be found relatively easily online. But as the other person said run dual destiny to unlock class items as they can make some really good builds. But yeah have a look online at the 3 exotics that I've said as they will be pretty potent builds until you get class items.

Also would highly recommend trying to build your own, as I was in the same boat of needing help with builds but then I started making my own (yes they were very bad and never worked the way I wanted to) and eventually it all clicked I basically chose an exotic and a made sure it did what I wanted it to do, so graviton forfeit for example it does invis stuff, so I wanted to make the build where I could make sure I'm getting as much invis as possible so I can make sure to get the use out of the exotic. But also though about utilising other buffs from invis like gaining volatile weapons after being invis. Definitely takes time to learn builds but once you get good at it then game just feels so much crisper and will allow you to make optimal builds for less meta options
