Sorcerors: how do you build them?

Hey guys. I'm a big fan of sorcs in tft especially lategame with sol and karthus taking over the show.

How do you guys build your sorc setups?

Personally i've been going 4x wild buff +6x sorc in endgame but i'm starting not to like that setup very much and i want a beefier frontline then my wild minioons can grant me.

I've been thinking of going guardian with kass on one side and lulu on the other as a 4 man frontline but i'm not sure its worth it.
