EVs are simple; maximised special attack, then the rest help to get the best out of its special bulk.
I believe this is the best we can get out of Elgyem. It doesn't have enough bulk to set up Nasty Plot without getting hurt (I tested this). Sadly, Abra beats it in an offensive role, and Solosis beats it in a defensive role. There's always the support-mon option and TR is somewhat of an option if you opt out of Analytic, but otherwise, this is what we have.
