We're already up to the tenth entry in Pocket Gamer's yearly advent calendar giveaway! Doesn't time fly when you're giving out free codes to some of the best mobile games of the past twelve months? If you've not heard of our advent calendar before, that's exactly what it does - every day in the lead-up to Christmas you've got a chance to bag a copy of an awesome game.

Today's game is the awesome deck-builder Mystic Vale, and we've got 5 Android and 5 iOS codes to give out.This isn't your average lay-down-cards and mash-monsters sort of a game though - instead it sees you trying to restore the magical energy that's been sapped from the land. Sounds pretty cool, right?

Mystic Vale was one of our games of the week when it came out, and we said "this is a pretty complex experience, and you're going to have to learn the rules if you want to get the most out of it - but if you're of that disposition, the time you put in is going to be well worth it." Click here to read that entry in its entirety. Or check out the trailer we've embedded below to get a better idea of what the game is all about.
