It's terrible, just farm best you can, try to not get pushed in or froze on. They will most likely dive you early since it's the only time you're killable. Survive early lane until lost chapter and everything is great. Being behind in cs and xp is okay, you spike on 1 item (everfrost), and your passive gives you xp. Just make sure to understand that you don't play zilean mid to one shot opponents, most of the games, you will just perma waveclear with bombs, try to get prio and roam with the strongest member of your team.

Group up! Play with your strongest member, jungler, adc, mid, whoever it is, you need to peel, slow, stun, and do everything for them. Watch for sidelane tho, you're very fast, so don't hesitate to pop up in the lane the ennemy is splitting in, wave clear the wave with a few bombs and zoom back to your team at 300mph.

If you have an hyper carry the game is won at this point, just group up and let the Zilean take over, always remember that in game e'ing an opponent is better to secure a kill, but e'ing a hypercarry in lategame is usually the best option. So for example, let's say you're playing with a jinx 6 items, pressing e on her in late game teamfights will most likely win you the fight. However, if you see an ennemy of position, e on him. That way you will secure a kill. E on ennemy = ennemy out of position. E on ally = ally out of position, or chasing.
