I'm thinking some combination of Slivers and 20 Enchantments prison deck with Replenish, and 2 enchantresses and this deck should be able to rifle out 8 to 10 enchantments and a couple dozen copies of enchantments within a couple turns. Which means you would draw a card for each COPY of an enchantment which enters the Battlefield for EACH Enchantress you control. Meanwhile, you're getting enough mana of each color to "fix" a sliver deck and drop all your 5-drop bombs within a couple turns.

What do you think?
