Obviously no one wants to give away their current tech -- that's silly. But once your deck is taken down (assuming it wasn't Top 10 and thus something you hope to resubmit later), there's no point in not sharing your experience with it. Here's the first deck I submitted to the Arena, which did quite well for itself, peaking out at 5th place:

The card I spun was Obsidian Pillar. 8) At 78th level, it had all of the bennies except it only started with 180 HP.
With 12 Pests, 12 Rewinds, and 8 Nightmares, there's a lot of denial in here. 4 Steals don't hurt either. When I retired this deck it was because I was so happy to have spun a Nova -- ironically, the resultant rainbow denial deck I built didn't do nearly as well as this beast.
