Ok so my favorite deck so far is my Spider-Team deck, I used it in the tournament. It is not perfect but it is fairly balanced. Big weakness is if you level up too fast you are at a disadvantage mostly. (Man a few of those super rare return power to 1 would be cool)
Anyway I like it cause its fun to play and it can surprise even me. Anyway to share my last game from last night, a non CBR friend must have been at card challenge because kept bugging me, (might not know you can play anyone) so I won first game with my X-Men deck then figured I would try my spider deck and I was LOSING REALLY BAD, I mean by like 20... super bad luck. A lot of cool cards were lost to damage... and I wasn't getting good ones either.
Anyway eventually I played two "Web Slingers" in a row, these hit for 1 every-time you hit 2 or more with a level one card. (even when I put second one out) Ok so I have those out and am losing bad, probably worst ever with that deck. I get a Yoink card, and retrieve a "magnetic personality" card, it draws another "magnetic personality" card, and then a "super spider squad" card which I buff. (but it got blocked pretty quick) All of those are level one cards. So I did 16 damage in one fury of cards and only one keeper got blasted in last attack.
Now I still lost but if I had played the other of the two cards I had left good chance I would have won. It was still fun though! (wasn't right before that however)
Congrats & apologies if you read whole post!
