For better minion wave clear, press empowered q with hydra or empowered w without. Stay at bush and jusmp for last hits.
Pros / Cons
When against a melee ad champion like fiora, it's a difficult lane, ask for help from your jungler and wait for gangs to kill. When against a melee ap champion like cho'gath, it's not that difficult, just dodge all his abilities and then it's yours. When against a ranged champion like teemo, try not to get poked down. Stat at bush, jump (passive) for minion kills and wait until a gang or level 6.
For the oneshot combo you will need at least 1 item. Press ultimate with 5 stacks of ferocity. Press youmuu's ghostblade before jump, press empowered q after pressing youmuu's and before jumping (tip: press oracle alteration when you press ult to be sure he didn't see you). Jump with empowered q and in-air press e, w, Hydra. If he died, you did good, if he didn't, just press another q, he will be dead. Be careful not pressing e before jumping because you will be visiable again and you can't jump.
When you want to jump on somebody from a bush (not for oneshot), jump and then press q for auto attack reset. When you are getting ganged and you are low, stay at the bushes, place 2 wards at 2 bushes and when someone comes to you, jump to him and go to the other bush, then when he comes to that bush, jump again to him. Keep doing that until you kill him and try getting stacks when jumping from your abilities. If you are low, press empowered w from the stacks will you get for life back.
