[S-TIER] Berzerker Electric (or Poison)
With the buff to Berzerkers and Electric, this comp is a lot stronger. It also counters the Blender comp since Olaf's glacial procs can shut down Nocturne. The Electric trait was buffed in Patch 9.24 and is much stronger in the early game, dealing 100 damage each proc instead of 70. Use Electric early to stay healthy or winstreak. Zed 2 with good items is your win condition.
You can also go for the Berzerker Poison variant of the comp by dropping Orn and Zed for Twitch and Singed. Poison is better in a lobby with many Summoner or Mage comps.
