Squads with Silver IF's don't show up in the cheapest SBC solutions list
Squads with Silver IF players don't show up in the top SBC solutions list.
Silver IF's can be used similar to normal Gold Informs, as long as the SBC doesn't specifically require "Player Level: Exactly Gold".
For example at the moment "Any OTW (Tradeable)" SBC could be done for 5.5K cheaper (36850 vs 42500 coins).
First I thought it was a thing to prevent "pricefixing" cards with less supply, but as I just checked there's less Gold IF 76 Dalmaus (211) on the market than Silver IF Chairs (280 cards).
