I've tried a mono-aether deck in trainer against DM, but there are quite a few downsides:
- Titan cannot be stopped, so you need some healing
- Chargers can only be dealt with after their damage
- Extra pillars/towers always welcome to get past the draining
So you probably need SoGs to heal you (at least 2 in the field), Phase Shields to protect damage, and Lightnings/Lobotomizer against Grav Nymphs and Chargers. And then you still have to do some damage yourself >.< (good thing Aether has immaterial crits to protect from Otyugh)
