Shurima reunited

I got a new a**hole torn open by a xerath supp the other day, (i don't remember his adc, but he was the issue.) so I came up with what i feel would be a pretty nasty team.

Nasus/renek top Nasus/renek jg Azir mid Sivir adc xerath supp

Thoughts? I don't know enough folks decent with any of these champs to pull it off, but it sounds terrifying.
