Zilean

If you plant your Q on an invis teamate teemo it will also make the bomb invis, you can also place bombs on J4's banner and if it expires before you bomb it still goes off. Sometimes placing a bomb on your initiator before they go in can really do some damage to the enemy team, a malphite zilean combo can be pretty devastating.

Um...let me say he is VERY fun! He may not be super strong or a dominant champion, but he has this thing about him that makes him so fun. His bombs are trolloish, and late game with Max CDR it is actually possible with rewind and your speed boost to have that continual boost throughout the time you're moving. With Homeguards, Lucidity Boots, and my continuous boost of speed, I had about 800 MS. It was so funny watching the enemy trying to catch up to me.

I like to play mid, I'm not really that good at mid lane but zilian is super easy.

He's so easy to play there's really not much I can think of in the way of tips...

Except; If you're against a melee champ like fizz, you can put bombs on your minions and he'll either have to eat the bomb or miss CS. It's extremely troll.

Riot has gone to great lengths to make your teammates aware you've put your ult on them, but they will still ignore it and completely squander the ult so you need to treat your ulting like you're lasthitting minions. Wait until the last possible moment to ult allies to ensure they actually use the effect. It has the added benefit of baiting enemies.

You can also bomb your allies that are close to death to possibly dissuade low-health melee enemies from finishing them off or risk dying themselves.

In lane, the easiest way to deal with Zilean's poke is to walk into your own creeps, let the bombs explode, and force him to push his lane. Zilean has little mobility to retreat from a gank. Keep that in mind as you bomb the enemy.
