If you're still open for ideas:

Controlled Forces

Zilean controls all damage that is taken by a unit and stores it. Zilean can toggle the buff on any unit and has a range of X to maintain.. The spell costs 0 mana each second but each damage stored up to a certain threshold is stored. Casting the spell on an enemy dispenses that damage over a period of time.

e.g Zilean casts the spell on himself for 0 mana per second. A Volibear deals 50 damage to him. The spell now costs 25 mana per second to sustain. After Volibear does a total of 250 damage Zilean stores up to 250 damage and it costs 125 mana per second. Zilean casts the spell on Volibear and it does 250 damage over 5 seconds.

Linked Time

Zilean links his time with another units. When that unit takes damage X% of it is transferred to Zilean. It costs X mana per second and has a range of X.

Trapped Time

Zilean creates a rune that stores damage in a radius around it. Zilean can cast the spell again on a rune to disperse the damage evenly to all units around it. Zilean can have up to X runes at a time and they are global.
