What ruins tournaments is inviting a guy who plays at 2900 level with little security measures and barely at GM level once those are introduced (happened at Sinquefield cup). It doesn't help has cheated in the past and plays his best chess consistently when there is live broadcast going on.
Magnus isn't yet feeling his age chess wise either. He wins most tournaments he enters, including demolishing 4-0 a guy who won the Candidates twice in a row (the most important tournament in chess for every player who isn't currently a world champion) and he is league above others rating wise.
