Pick Nunu, buy tracker's knife/Tiamat/shoes ASAP. If you see the enemy jungler Ever, go invade where he isn't and Use Tracker's / Control wards to watch YOUR jungle entrances and try to get your not-so-dream-team to collapse on them if they ever think about gaining exp. Literally be useless (but it's okay) Eventually You should have like Lucidity, Cinderhulk, Titanic, Righteous Glory, Locket, Spirit Visage/Knight's Vow maybe cleaver if you monster fed or Wit's End if you need both Mr and some damage for Mid-game.
You don't need mechanics, just punch and eat camps and be support #2 (with less bans, higher winrate, and less practice than Ivern)
