I've been doing some future card translations on another thread and I thought I'd share them all with you here in one handy post, it's great to look at these translations now and have a better understanding of how they'll effect the game.
Disclaimer: I did not translate these, an old forum member by the name of giantbadger did...so I'll give ya as much as he posted.
