I was just looking at the ways I could enhance mana differently than before, and looking for a way to bring in Giant Adephage. I achieved the former, and the latter was almost a casualty of cuts. It probably should have been. An early batch of cards included Verduran Enchantresses and was focused, outside of creatures, on enchantments. That got me considering some enchantment creatures, but those that remain are there because they provide special benefits. A last-minute cut of two copies of Worldspine Wurm for a pair of Ulamog's Crusher leaned out costs and gave me a little easier to cause destruction (via annihilator). The curve is odd, averaging 2.89, which is not bad given the 14/7/5/2/6/1/1/2 curve.
