I've been following him since set4 came out and I climbed to Gold in few days.
My recent matches are: 2nd, 3rd, 1st, 1st, 2nd, 1st, 4th, 2nd, 1st with various different comps.
I got first places with: Dusk/Keepers, Cultists, Divine, Duelists.
I think these comps are really strong and if played well, you can almost always end in top3 playing any of these. Of course, depending on item drops and what other people in game are playing
