Looking to pick up some staples!

As ideas are brewing for decks to build, I find that I need staples! I'm mainly looking for mana fixing stuff i.e. Ravnica block Karoo lands and signets, but there's some other stuff I'm looking for too! Start up a trade if you see anything you want on my list, and we can try to make something happen!
