Farming:
Poppy - play safe, hug tower, last hit, don't push, bait enemies into tower dives and rape em !
Tip: Starting with Paragon of Demacia will help you farm in early game.

Jungling:
Shaco:
route 1: Enemy red -> Enemy golems -> TRAP DEM WRATH BUSH AND F-F-F-F-FIRST BLOOD !
route 2: Wraiths -> Red -> Blue -> GANK ENEMY JUNGLER AT HIS RED AND F-F-F-F-FIRST BLOOD !
Tips: When you counter jungle with shaco remember: his buffs respawn every 5 mins, take as many dragons as possible as soon as you get your bloodrazor and most important : ALL JUNGLES ARE SHACO JUNGLES - Siv HD
