Alright, so you start with buying a corrupting pot. Once you get to lane just farm and try not to trade until atleast lvl 3, since you will lose all of them. Once you back you buy a tiamat and TP to lane, at this point just farm and watch out for ganks.

Once you have some items under your belt its time to push. Try to tell your team to start a fight and draw attention. Once this happens take down one or two objectives and see if someones coming to stop you, if they are you have succeeded. If they only send one person to stop you you can probably take them down. (a quick combo guide, Press E and jump in with Q, get an auto attack off and press E again, then press W and activate your titanic hydra,the just continue autoing and using W). If they send more people just back of, by doing this your team can pretty much take whatever they want.

Try to teamfight as little as possible, you probaly think your team is just a bunch of boosted monkeys anyway.

You dont have any sort of multi target damage except youre E, try to fight 1v1 since youre a god at dueling.

Youre Q can jump to pretty much anything, wards, minions, champions, monsters etc, make use of this to escape or engage.
