Well.. I felt like it would be wrong not to mention
Scroll Rack, because Yuriko really benefits from it, but the price really hurts.
Besides that, I'm always glad to help.
Btw, about your land base. Take a look at the lands that always enter tapped (
Bojuka Bog, the cycling lands, etc) and think about you really need them. The bonus effects may be nice, but are they really worth slowing you down by
entering tapped?
Especially
Bojuka Bog I've cutted in all my decks, because in 95% of the time it has shown up at a time where I couldn't benefit from it. Especially in UB, we got a way better option:
Ashiok, Dream Render. He should fit into your budget and solves 2 problems: Tutors and graveyard hate.
