Prioritize Skill 1, your main offensive skill, then level the skill that speeds up your allies.
Poke with Skill 1 Time Bombs over the enemy minions and give your ADC a calm lane to farm. The double-bomb stun combo in particular is the key to taking control of the early lane.
Use the movement speed from Skill 2 to roam with your jungler. Catch enemies with your slows and speed-ups. In small fights, put Ult on the focused ally carry without hesitation and win the forced fight.
Late in the game, stay with your hypercarry and keep them buffed and protected. When an enemy assassin commits everything to dive, the Ult revive turns that effort into nothing.
From the back, speed up your carries and support their kiting. Throw bombs into the enemy formation for AoE stuns to break it up. Who gets Ult decides the fight, so keep your eyes on the whole battle.
Zilean's Ult revives an ally, but a common mistake is underestimating enemy burst and holding it until the ally is already dead. The revive effect lasts several seconds, so it is safer to cast it the moment an enemy assassin starts their burst, even if it feels early. From level 5, keep watching your carry's health bar and the enemy's movements.
Attach a bomb with Skill 1, speed up with Skill 2, then stack a second bomb to stun.

A three-step guide set by the official champion library. For difficulty, a higher number means harder to play.
Critical damage is 200% for every champion. These figures exclude items and runes.
Our take
Time Bomb loses base damage at every rank, slowing Zilean's wave clear and his lane poke. Chronoshift is 10 seconds longer across the board, which raises the cost of spending the revive at the wrong moment. Against a team that forces fights back to back the second one often will not be up, so deciding when and on whom to use it carries much more weight.
Our take
Chronoshift gains 10s of cooldown at rank 1 and 5s at rank 2, with rank 3 unchanged at 70s. Through the mid game, where fights come one after another, Zilean gets fewer guaranteed saves, so choosing who to spend it on carries more weight. The refund when the revive does not fire drops from 15% to 10% as well, which raises the cost of casting it speculatively as insurance.
