How To Enjoy Playing Lizardmen?

Looking forward to the next DLC mainly for the Beastmen but it annoys me that despite trying, I've always struggled with playing lizardmen. I'd normally get to about turn 15 and get bored with them.

Been wanting to give them another go before the DLC comes out and would appreciate any tips on most interesting units and LLs to pick.

I play on normal and have all the DLC available.
