What new 99-rated card tier did NBA 2K19 add to MyTeam?

NBA 2K19 added Galaxy Opal as a new 99-rated card tier in MyTeam.

MyTeam is NBA 2K's collectible-card mode, where players assemble custom rosters by acquiring player cards, uniforms, coaches, and other items. In NBA 2K19, Galaxy Opal was introduced as the top classification for cards with an overall rating of 99. That made it distinct from lower tiers such as Amethyst and Pink Diamond, while Dark Matter became associated with later NBA 2K card systems rather than this specific NBA 2K19 addition.

The Galaxy Opal label was more than a cosmetic name: it communicated that a card had reached the maximum overall rating in the game's classification system. MyTeam cards could be obtained through packs, rewards, auctions, and other in-game systems, with their values shaped by attributes, positions, badges, and player popularity.

NBA 2K19 was released on September 11, 2018, for Windows, Nintendo Switch, PlayStation 4, and Xbox One, with mobile versions also available. It was the 20th installment of the franchise and added the Unlimited mode, including competition connected to a $250,000 tournament. The game's heavy use of virtual currency and microtransactions also drew criticism.
