HEX: Shards of Fate just released a really big content patch and added this bundle along with it! Hex is a digital trading card game with complexity level similar to Magic the Gathering and I've been playing it for a long time. It's free to play, so if you haven't tried it you should give it a shot!
This bundle contains a lot of PVE cards, some PVP cards and some other things, hope it'll be of use!

If you need some music while playing, consider following me on SoundCloud at https://soundcloud.com/nollfem where I repost tracks that I like!

It is a Steam gift, not a key, so I'll add the winner as a friend on Steam to send it.
