I use this card so much... it is absolutely devastating. I pair it with Spirit Miner a lot.
To be honest I haven't bought many new cards in ages... I'm still waiting a chance to sell my CL packs for a profit to buy new cards... but I'm guessing the price of those won't rise for a long time. I'm using my SPS and DEC to buy the new RW packs, but again I want to sell those after they sell out and then buy the cards I need... so my strategy is to... wait.
