That 200 cards can either be player cards or classic cards. Remember classic cards are unlocked by reaching milestones in steals, rbis, runs scored, home runs, hits, strikeouts. You can check the requirements for classic cards and player cards on the back in your card collection and see what you need. Then just do what you want, here's the tips.
1) For homeruns make sure to press up on the control stick and aim for the short porch
3) You can get a friend to meet you in a ranked match. Whatever you want to work towards, you work towards.

I just adjusted all of the teams rosters to have one team really bad and whatever cards i needed i would just adjust their stats and make them good. Its kind of time consuming but it makes getting the cards really easy. I found just playing against one bad team the whole time easiest.
I also used this excel sheet to keep track of the cards.

if you can find someone that has the cards that you need, you can play a ranked card game together. as long as you accomplish the goals for each specific player whos card you are going for they will unlock for you at the end of the game the exact same way they would if you got them in a single player game. and if you have someone helping you out it will be way easier to do the tasks to unlock all of the players that you need.
