I like the idea but they could really expand on it for other cards.
Example. I like the Braves and plan on using as many Braves players on my team this year as I can. So how bout cards like TA Albies could get the Prestige power up as I finish stats with him? This could go for any card really. Collect the player and get rewarded for using them.
I see a lot of potential here and this would be great for players who want to use specific cards as long as they can.
