yeah, usually i go for something like the crystal scepter, but usually since its so late game I end up trying to get as much AP as I can so I can 2 shot enemies at lv18.

Another note for others, where I've put (Best Build), I dont mean its the "best", I mean its the best out of all the builds I use for Evelynn :P

You don't really need two deathcaps eh? It's kind of a waste if you are just buying it for the ap. Just go for something that gives some ap and some other unique passive. My two cents
