Either a new shard card, OR a quest, after you acquire a certain score, you get x2, like... 10,000, x3 at 20000, x4 at 35,000, x5 at 50,000 and x6 at 70,000... it'd be cool, but unfair against top 50's since all their scores are mad high, and most of ours are not. SO! perhaps we could leave the top 50 decks without the mark quanta multiplier for fair game. No doubt adding goals would make the game more interesting.
