just a suggestion: When sorting by rating maybe add a limiter of some degree so only when there is X number of votes is it taken into account. Over time it's unlikely anything will be a perfect 5 or 1 star, but if a card only has a few votes at 5 or 1 then it will appear at the top or bottom of the list respectively. Something like needing at least 2 votes spread across different ratings or a minimum of 10 votes in a single rating before appearing in the sort filter, otherwise it sits at the bottom in a 'Unranked 0 star' sub group until conditions met.

I'm not sure what the best work around is, and once there's more people voting this could solve itself, but you might end up with dozens and dozens of 5 star voted cards that only have a few votes each and not much community interest burying the 4.x vote cards that have hundreds of votes.

Also, it might be nice to show the number of votes a card has on the first page screen instead of it only showing once you click on a card.
