It is probably because I am a dimwit, but I don’t really understand the rewards for doing the daily horde challenges. Today the rewards were 6 cards for Incon, 3 for Advanced and 1000 XP for Beginner. So far so good. I assume that doing it on Incon willl get me 9 cards plus 1000 XP on top of what I’d normally get (4 cards for Frenzy, so a total of 13 cards?). But then it also says Double Cards 4/4.

So someone with more brain cells than me, can you please put it all together and tell me what it all means? How can there be double cards, when you always get 6 cards for a frenzy run and 10 for a 1-50 run regardless of difficulty?
