Sheldon is auto-included in every ST deck at the moment and one of the reasons why ST is such a strong faction. I like his ability but I think his provisions are set too low. Because he brings massive points on the board, most of the time between 14-18 and he only costs 8 provision. So you can see, much more points than an Old Speartip for 15 prov. does and the only condition to set him up is to have the card in your hand. In comparison to other high provision cards, like Regis or Zoltan, it's an easy thing to get the points out of him and there is no way to counter him or play around (only Shilard). Furthermore handbuffing is a strategy with carryover, so you have to regard this too. In my opinion he should get more than 10 provisions, maybe 11-12.
