VIP

VIP memberships were introduced in May 2019 and pitched as a way for players to "achieve better rewards faster through game progression without detracting from the fun and engaging experience of the game". There are 3 levels of Plan offered.

Renewing a membership increases VIP Tier, leading to bonuses.

Other than boosters, where Master simply gives twice as much for twice as much cost, the difference between Pro and Master is of quality more than quantity. Pro gives more Legacy rares, and Master gives more Mana Jewels.

A common strategy is to not open Legacy Booster Packs until all Commons and Uncommons and Rares are acquired, by free packs and Booster Crafting and VIP plans. The packs are forced, since they are non-duplicate, to be filled with only Mythics and Masterpieces.
