Quote from entombedhydra »But I'd ask you to compare Jeskai Sage with Jeskai Elder; 1/3s with the latter ability often cost , so I can only assume that prowess costs next to nothing on Jeskai Elder. So if Jeskai Elder is a fair card; I think a 1/2 for prowess is more than fair; and thus - again - we're talking over + for "When this dies, draw a card."
Sorry that I'm not responding to your entire message, but skimming over it this part stuck out to me. Scroll Thief Jeskai Elder ain't. It loots, not draws.
