If you submit a team and your opponent surrenders or flees, it will now count toward your quest (if the team you chose matches the quest splinter of course)
Gold cards will now show by default on team selection if they are higher level than the corresponding regular foil card

I love the changes! Both of these things have been a minor annoyance for me, so it's great to see that this is a thing of the past. I'm more tempted to get more foil cards now that they are more easily usable (yes, I'm that lazy :P).
