Starting with 1/15 (out of 36) required, I'm trying the 'Putting The Ball In Play' mission for the Diamond Pack. Managed to get up to 8/15 for about 1500 or so, but now the players start costing more
That being said, they're all really good cards for when tournaments come around anyway, heh
(Edit: now trying to combine with 'Chicago White Sox: Fox And Apraricio', which rewards a Diamond Pack and an SE Nellie Fox card that works with the first mission. Now quite sure I'm just throwing my saved PP against the collection wall, but at least I can sell all these again if I reach a dead end
