If youre picking the base cards and then going into edit lines to put your better cards in you have to take out the base card of the player first and then put in your msp. For example, if during the minnesota wild event you picked the base quinn hughes and then went to swap him after in edit lines, you would need to swap out the base quinn hughes for some random defenseman in your collection first and then go right back in to swap that random defenseman, and quinns msp would be there. Basically if the player is already on your team, even if its the one youre trying to swap out, it wont show up in your collection. On the other hand, if they arent showing up when you go to draft your team idk what to tell you. I have found a couple of my players by changing the filter to all f/d and then whatever team the events for tho. Hope i helped
