Gatecrash

The more I read about him, the more convinced I am that Jace Beleren is the Poochie of the Magic universe. He's the main face/mascot of the game now, the same way Urza was in the early years, but he feels forced into the storyline, rather than seeming like he belongs there. And there's enough going on here - between the mental vampire Mirko Vosk, the mad scientist planewalker Ral Zarek and his goblin assistant, and the tripartite dryad mind of Trostani - that Jace's presence really isn't needed, and takes up precious space that could have been spent on the Ravnican story.
