The higher priority things on my wishlist are to assemble a few modern/standard decks.  The rest, and what is most of my wishlist, is filler for EDH or a pauper cube.  So I'm fine with bulk swaps, but I'm not looking to trade down too much.

Of the semi-valuable stuff on my wishlist, I'd prefer to trade it for my highest priority wants - shocklands/fastlands, stuff for hatebears (aether vial, aven mindcensor, thalia, kitchen finks); reanimator (Iona; griselbrand); affinity (glimmervoid, arcbound ravager, blinkmoth nexis); and teysa EDH. 

I'm always looking for fetch/dual/utility lands.  Propose away, never hurts to ask, even about small trades.
