Plateau'd ? Not sure where to go from here...

Aside from Uugo, I feel like I have no targets to 6 star. They all seem like kinda niche/FW champs only. Relatively early to the game (middle of 4th month), and am on 3key nightmare CB (close to 2 key). Nowhere near close to hydra chests. Do I just keep stocking up foods and waiting to pull more quality champs? Kinda feel like i've plateau'd here.
