There are some F2P players that saved their gems for situations like this. It's quite likely that some F2P players already have a full working Vendread deck.
If the next box contains new strong deck, those F2P players won't be able to obtain it since they already spent all their gems on Vendread. But you guys would still repeat the same thing: "This new box is new meta. F2P never left this game"
It's more simple if you just recommend F2P players to create the 2nd account so they could reroll each time Konami release new interesting box. But obviously you won't do something that doesn't give benefit to your own business. Because your goal is to make people run out of gems and start spending money, thus you can easily ask them to join your discord
