At release, all icons in packs.
At release, a mid and Prime Icon SBC are available for all players. Immediately.
Mid is basic requirements, each tier of icon have the same requirements. This will balance the market and value of NIFs making there value in packs and enticing people to open packs.
Primes all require the submission of the mid and that the mid is used for say, 250 games. The 250 games removes the 84,85,86 SBC submissions giving you reasons to use the cards.
Then when PIM are released, it’s only the select few that are deemed worthy - all PIMS on market though. And a similar requirement where you can use the Prime for a set amount of games to lower the cost.
Obviously there are holes and this is kind of a shoot from the hip idea....but I like the idea of all year working toward say a Prime Gullit by using his other versions.
