The mono-aether i use is 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61r 61r 61r 61t 61t 61t 61t 61t 61t 61u 61v 61v 61v 61v 61vWorks about 22% on FG's, but only on a few. Pretty decent for PvP and AI3's as well.
I've played around with a variant close to that, but I find that Immortals are far more effective than PUs (at least for this style of deck, certainly PU has its place in other decks)). Firstly, a lot of decks have ways to counter you stealing their own creatures if you can't Quint the PU'd creature right away: Fire/Aether will burn it, Ice will Freeze it, Gravity will Grav Shield it... and so-on. On the note of Gravity Shields, Immortals are going to be your only answer against a Gravity-based deck once one of those shields touches down.
Another thing of note is that Immortals ARE capable of more damage than Phase Dragons when played in a certain way. Keep in mind that an Immortal is 50% of a dragon (both in cost and damage), so if you can place an Immortal this turn and the next, then you're going to get more damage than if you wait for the Dragon. Basically, on Turn 1 the Immortal does 4 damage (we'll assume un-upped), then on Turn 2 and onward the two Immortals do 8 damage a turn. So by placing two Immortals over the course of two turns in a row, you received 4 extra damage than if you had waited to place the Dragon.
The only real saving grace for PU is against the occasional creature-stomp deck, but against anyone who isn't about big creatures (or is able to Quint their creatures), your PU is just a dead card. Meanwhile the only real counter against Immortals is a Titanium Shield (
http://elementsthegame.wikia.com/wiki/Titanium_Shield), but Earth kinda already destroys Aether when played right (Oh I'm sorry, were those YOUR Pillars I just destroyed?). I'll post the deck I've been using the past couple days, I find I rather like it:
61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61o 61q 61q 61q 61s 61s 61s 61t 61t 61t 61t 61t 61u 61v 61v 61v 61vIt's a standard "Hide behind your shield while your goons do the work" style of deck, except that I swapped a couple of the goons out for some Lightning to take care of the occasional problem creature. Things like Devourers, or spawners. It's also a nice way to keep Empathic Bond down a little. So far it doesn't have any problems outside of the usual Aether-killers like decks that destroy my shields a lot, or ones that are able to choke my Quanta-production, and even those I sometimes managed to struggle out of by the skin of my teeth.
