I was playing Pod for quite a while, but it fares very poorly against Tron. It can win, but it's a match that you want to dodge and has become so prevalent that I recently switched away (sorta bummed too. I was about 3 cards away from having all the deck promos). I played Scapeshift at Modern night last week and it actually ended up being a lot more fun than I would have expected for a giant pile of cantrips and a fragile win condition. I need to work on the sideboard so that I'm not cold to Slaughter Games, but at the moment I'm thinking about keeping it together for the next couple of months in preparation for GP Richmond. I have no illusions about doing well in the GP, but I'm going for sure. GP Charlotte was a blast.
I also tried out Grixis Delver but it's just not my kind of deck. UR Delver probably is more consistent, and another friend has had some success with it. He's moving into Splinter Twin once he gets all the cards. It's definitely a very strong deck that I haven't had a lot of experience combating yet.
