My red holdings lacked enough double strike to keep them in. Instead, I focused on building double strike, banding, and enchantment creatures into a deck that can hit hard a number of ways. There are 12 aura cards, plus another 4 ordinary enchantments, collectively able to add oomph to both Sage's Reverie and to Ethereal Armor. All non-aura enchantments are pulling double duty by being enchantment creatures. The result is that every creature has (or can have) double strike, has banding (often with first strike), has or grants protection, or is an enchantment on top of everything else, with some meeting more than one of those conditions. The 19/8/9/4 curve comes in with a quite lovely 1.95 average.
