Minion Dematerializer : You already have so much clear when youre AP, with this rune you will have enough wave clear to roam after your lvl 6 (use one charge on melee minion, and two on cannon minion)

Cosmic Insight : You have 3 activable Items (Zhonya, Rocketbelt, Gargoyle) with this rune you get such a cooldown reduction on them its broken (keep in mind that you have 3 of them ...)

Manaflow Band : You will need a little boost of mana for mid / late
