Here is a deck I put together for the purpose of getting special spins and making money. Silver arena provided a good winrate, and with EMs can make decent electrum. This deck is also very effective against halfbloods (not convinced of their value).

For my first hundred games test went W/L: 84-16 TTW: 10.3 EM: 25 Spins: 16
The TTW is higher than other arena decks, but more EMs and ending with more HPs might make up for it in the electrum earned category. If anyone else wants to test it and give feedback that would be great. Next time I play for an hour I'll track the electrum gain.
How I play it:
Having to discard is fairly rare, but I usually discard flesh recluse, or a double permanent (hourglass, fog shield, pulverizer). Do not discard SN, Fog or Pulv if there's only 1 in your hand. Save blessing for Vamp and TU vamp, or Lava is second option.
oh and don't forget to back off the hourglasses if you don't have enough dmg out towards the end of the deck.
