Opening Box is best way to depo... they contain normal,r are token, amps, and while easter are more for high enf players with 5 ped egg inside that give buffs, xmas boxes contain candies that are free buff (1 pec each) although less powerful.
and key purchase from web shop does not apply the "depo tax" that we all hate
(a note for UK players, your court did not ban boxes in game last week....enjoy)
