Upland.me and BlockChain Heroes combined to create the Titan series. The cards went on sale 4/6/21. They sold out in minutes. Titan packs have 25 cards, and guarantee 3 Rare and 1 Epic NFTs. The packs have a 60% chance of a Legendary, a 10% chance of a Mythic, and 2 opportunities for the true 1/1 collection.
Upland game is huge. https://r.upland.me/uSUa Blockchain hero cards can be valuable and Upland is arguably their largest partnership to date.
Get them while they can, and good luck.
