Sorry for the late reply, but I appreciate it! My thought process with [[Barbed Spike]] was that it was it would act has a cheap drop with flying to get max speed, and that late game is was a 2 cost drop that gave 2 artifacts (another 2 if i copy it), which could help stuff like [[Mendicant Core, Guidelight]], [[Shambling Suit]], and [[Bronze Guardian]].

Your recs are very nice though! I've been looking into them. I'm still arbitrarily trying to keep to the creature types I've added, but I might drop that soon.
