Supercard? I quit playing that shit when I hit the brick wall with Super Rares where you have to start playing KOTR and special events in order to get better cards.
The main thing I dislike about it is that even though you increase your tier, the pulls don't correspond to that. Like I'm in epic right now, and you always pull one card for that tier when you get there, but the whole "get to epic+ and epic++ to have a better chance to pull more epic cards" feels like a lie. I wish you could only pull from your tier and maybe the three under it. So like in epic it would be ultra rare, super rare, and rare. Uncommon and common cards end up being most of what you pull, and it's frustrating. You can make pros in those tiers no sweat, but pulling two of the same guy in super rare or higher is basically impossible.
Either that, or let me pick which cards I want if I want to buy. Maybe everyone would buy the same ones, but I only want old guys. Having Rusev or that fat bald guy in the Wyatt family doesn't interest me.
I played 5000 games and finally gave up. I've moved onto the superior card game nba2k15 mobile. More game types better rewards and it doesn't feel like a time sink like supercard.
Problem for me there is that it's basketball. At least I kinda sorta once in awhile enjoy wrestling. I haven't enjoyed basketball in almost 20 years.
