If you want to have a real shot at topping the leaderboard of Cyber Arena, you'll need a decent deck of cards, in the form of AnRKey X NFTs.
Each NFT has a power level:
When you join for the first time and buy your battle pass, that will act as a Lvl4 card. Other cards from Lvl 1 to 3 can be obtained by redeeming oracle shards in BattleWave 2323 or by purchasing from online marketplaces.

Character based NFTs will become more powerful in Cyber Arena v2 onwards, as we will be adding metadata characteristics to them to offer a more strategic gameplay.
