[Comp] Zoners

Based on the most efficient zoning abilities, the point of this comp is to push the enemy team out of fighting range entirely, as often as possible.
For this we need the effects that nobody want to stay on/nearby... not just Sunfire Cape level, i'm talking Anivia Glacial Storm level.

Items

Shard of True Ice: more persistent AoE slows; as a bonus, more mana regen for all.

Rylai's: even more AoE slows.

Runic Bulwark: if your team is less burstable and enemies can't dive it successfully to end the zoning, what can enemies do? (oh yeah splitpush)


Summoner Spells

Clarity (1 or 2): zoners happen to be mana-hungry Tear-loving ogres, so fill their huge manapools with this.
