non creatures i would run: Lifecrafter's Bestiary, Skullclamp, Return of the Wildspeaker, Inspiring Call, Harmonize, Rishkar's Expertise maybe a few things like Fade from History, Beast Within, Nature's Claim, Collector Ouphe is also really strong since you will be running creatures Sure, the mana doubling can be fun, but is it really needed

Near Mint (NM) is ideal, especially for collectors and older cards
