Meta evolves and u should do the same (look at flygon, there are more mixed than cb nowadays) so if lax is the primal sp def prepare ur shit for him... i mean if it got banned then prepare for chansey (whos even more cancerous imo since its so passive to play)
Is lax strong?? Sure, it does his work done like a boss just as metagross or weez. Its uber?? I dont think so unless that magical cb lefties 252 hp attk sp def w some def and body slam fire punch eq spower curse rest sub fire blast surf and pursuit set.
So prepare ur team for top tier pokes..pray for a good match up and keep your counters alive, i mean if u sac ur breelom when laxs still around u cant cry cuz u chocked bro
