ya the cube is very expensive. I mean, most of the power 9's in there. Like real ones. I have yet to play ancestral recall yet though. Silly "not getting it first pick" and what not.

Conspiracy prices are pretty unstable still. This set is unlikely to be opened much, so I'm slowly picking up the singles I want starting now. Mostly legacy staples and what not. This foil prices are ridiculous because of the legacy staples in the set: council's judgement is playable, exploration/stifle/Dack Fayden/etc. are all Legacy staples, so their foils are ridiculous. Brainstorm foils will always be ridiculous. Marchesa and Muzzio are high because EDH.

Bruna's a really easy build-around-me Commander. Just throw in auras you want and done. If you're hardcore for it though, her decks can get pretty expensive as you're hunting down foil eldrazi conscriptions and what not.

Just like you, I personally have a LOT of EDH decks, because I generally prefer to play with a lot of variety. :D
