Immortal creatures controlling my creatures, immortal creatures smashing my permanents, immortal creatures draining my quanta, immortal creatures killing my face? No thank you.
Take out the aether cards and obsidian towers and switch the mark to dark. This also eliminates the chance of not drawing 6 towers in a 90 card deck.
But you might still need some towers, since 12 pests and the mark means only 15 quanta per turn. That's enough once reached, but it may be slow to play enough pests to get the nymphs running. And false gods are generally very fast to set up.
It's an interesting idea, nymphs to use your creatures against you, steals to use your permanents against you.
I'd probably call it just Shadow; it's like you but against you. Sounds less clunky than Reflected Shadow.
Edit: Oh and take out the butterfly effects too, 8 steals is already more than anyone wants to deal with.
