Just some tips

You have some of the best early poke and scaling in the game
Early Game
You want to hard pressure enemy bot with q because of its devastating damage to targets in early game. Let your adc farm. If the enemy bot overextends you should be able to win because of the aforementioned high erly game damage. Try not to die, but if it saves your adc and you get a kill with death defied. Try to back for mana crystal or tear, but prefer tear
Mid game
Basically just try not to die and provide damage for your team. If a teamfight erupts, dying is fine in case you can get like 2 kills for it.
End game
You are kind of tanky and Zhonyas gives you artificial tankieness. Taking a few hits is ok kere, but still try to poke with your q and try to teamfight. Use your w to keep low enemies from escaping. Ult even if just one player is low to get the kill. Just ulting in teamfights is also sometimes worth it, because it gives a big advantage to your team, because everyone on the other team get low on health. You deal A LOT of damage late game, so use that to your best capacity.
