Obscuring Aether

Morph's support structure rendered as an enchantment: knock off every face-down creature spell you cast, which is to say every morph creature you deploy at its flat down payment. The trouble such enablers always face is that they sit dead in a hand with no morphs to discount, and they spend a card to shave mana off a strategy that already wants mana for the flip costs later. This one half-answers that complaint with the second ability, which lets you spend to turn the enchantment itself face down into a vanilla 2/2. When the enabling is done and the discount has nothing left to reduce, you can cash the enchantment in for a body and swing with it. That is a graceful out for an enabler that has outlived its usefulness, not a self-discount loophole: turning a permanent face down on the battlefield is an activated ability, and Obscuring Aether's own cost is paid in full regardless of how many copies you control. Note that the reduction cares only about the spell being cast face down, not where it comes from: cast a face-down creature off the top of your library or out of exile and the discount still applies. What stays unanswered is the timing problem at the heart of every reducer like this: a one-mana piece that wants to be on the battlefield early pays off only once you have assembled enough face-down bodies to make the per-cast savings add up, and a tribe that needs critical mass rarely has it on turn one.
