I started with this deck:
http://elementscommunity.org/forum/rainbow-decks/loufoquebow-(descendant-of-tha-gold-league-killer)(arena)/ and I've been adding / removing cards within games until I reach this:

I'm upgrading it as I win money grinding on silver. Is not the fastest deck i've played for grinding silver, but it have a high win rate. 13 wins 1 lose so far. Since I started adding and removing I can't say but I've spinned the wheel a lot =p. I don't think that this idea of deck can survive gold/platinum, maybe with other shards. I would maybe get in a few shards of braviness when I got em, not sure what to take out.
Also 4 wins and 1 lose in pvp2, but that is too slow for my taste right now.
I'm kinda new to the game, so any advices of how to improve it/balance are appreciated.
---- after a day of nonstop playing it I upped and modify it to this:

playing it against platinum and works really well for me.
