Why 30? Dead or alive, I doubt you could name 30 GM level players without opening a book or using Google 
can we declare Magnus a top 30 player of all time
@C-C-Coalback i'm assuming your username is supposed to be funny for people who know who that is (and i do)? 
You know, you should be sending this thread via pm to the one who managed to get fat thanks to a pawn diet (only if you want honest and accurate answers, obviously).
Winning every tournament and being world champion doesn't mean he knows how to play chess. Top one million
We can definetly declare Magnus in the top 30 ever. He is at least top 30 (maybe 31). He has won so many games and even has a higher rating than Kasparov. why are there so many haters? Did Alexandra Thesa influence this many of you?
also can we put ali in the top 30 boxers of all time also,i can easily name 30 boxers better than him.can we get real here ...lol

Magnus is the strongest player of all time. If that doesn't put him in the top 30, I don't know what does.
