There's a reason I haven't played this game in 2 years. Every time I'm in a battle to rank up. I suddenly can't get any cards I need to do ANYTHING. It's like the algorithm knows. I'm not even saying giving me cards to win. I just had 3 rank up battles where a drew only monsters that can't be played. It's a very common deck. This shouldn't be happening. But the duel links devs want to force you to stay as low a level as you can so you keep playing. It's done the opposite effect. Don't play
