Each time a tier box is purchased, it rewards one card at random from the current tier. Once all cards have been purchased from the current tier, the next tier is unlocked. Once Tier 11 is complete, the box resets. At some tiers, cards start above level 1. Cards marked ●● start at level 2, while cards marked ●●● start at level 3.
