I've been using this deck more, here's what I've found so far:
Pros:
60% or so win rate, more once you start to get upgraded cards
low cost for the deck, especially if you chose aether as your starting element
very simple deck, low chance of a bad draw
Cons:
Many shields (gravity shield and dissipation shield in particular) are problematic
If the opponent gets out discord before you have your shields up, things get rough
If the opponent gets a creature with butterfly effect out, they'll destroy your shields, Lobo/electro helps stop this though
If the opponent gets emphatic bond(s) out, you won't be able to do enough damage and will run out of shields and die
Devourer spammers (ie Decay) will kill you with ease
I'll edit this occasionally as I use this deck more.
The exact deck I am using is mark of aether, 15x aether pillar, 6x dimensional shield, 5x immortal, 4x phase dragon, 2x electrocutor for 32 total cards.
