Fnc Pioneer Key?

Im Fnatic fan for a year now. Im interested in buying merch and participating more in the community. I know Fnatic+ is a thing but i saw there was a system with Keys (Citizen, core, pioneer) before. I have no idea of NFT or Blockchains in general but on opensea i saw Pioneer Keys for as low as 55 euro. Wouldnt it be smart to get that and get a free jersey i wanted anyways for cheaper plus all the benefits for a lifetime. Am i missing something?
