Used every rare player in my brothers club (bar the 84+s) for the recent SBC's. Most people would respond by buying packs to replenish said players.
Used a lot of the non-rares to get players in the two player packs as well.
Despite all my efforts my best tradable TOTT was that guy from the Belgian league. 300k worth of players gone to sell a player for 20k. Annoyed at myself more than anything!
