Shouldnt be a problem then, owning 84 champions currently
Only missing: Caitlyn, Fizz, Graves, Karma, Katarina, LeBlanc, Leona, Malzahar, Maokai, Mordekaiser, Shyvana, Swain, Urgot, Wukong & Xerath...
With good luck, most of these will find themselves from the -50% groups so thatll be 5-7 weeks and I should own them all...
