Here are some lanes I think that are super strong:
Lucian/Braum: Lucian's passive works so well with Braum's passive. It's a match made in heaven. If you play super aggressive in lane and all the stars align, I guarantee you'll have a fun time.
Ezreal/Braum: Ezreal and Braum go really well together. As Ez/Braum, you have the chance to apply tons of pressure in lane, as Ezreal's abilities such as his Q/1 proc Braum's passive stacks. Not only this, Ezreal can dash using his E/3 and Braum can follow up with his W/2. Great lane.
Lulu/mostly any ADC: I think Lulu is one of the strongest supports right now. No matter if your ADC is playing aggressive or passive, Lulu can provide excellent enhancement to suit any playstyle. Not only this, Lulu is crazy good in teamfights.
Janna/an ADC you can trust: If you're premade with an ADC and also have voice comms, Janna can be a really great pick. She works well with most ADCs, but mainly hard carry ADCs such as Draven, Vayne, Jinx etc. I wouldn't recommend picking Janna in solo queue unless you know your ADC can respond well to your shields and tornados.
These are only a few recommendations and thoughts, hope this provides some insight :-)
