RE: Waka Flocka Launch Details!

The release of modern and wild format has less to do with the number of players and more to do with maintaining balanced meta as each new expansion brings new cards, abilities and combinations, which often causes a balancing issue even with rule sets mechanics. Also modern and wild formats has been around in other TCG for years for that reason if you ever played Magic the Gathering or Hearthstone you would be familiar with the formatting.

Also Splinterlands have released promo cards in the past not necessarily in this manner, which were also limited and difficult to obtain, and they did not break the game.
