=D this is such an amazing deck for pvp as well!
I did tweak it a bit, well.. not a bit but.. xD
I first changed the mark to Darkness (Oh, big change) and put another vampire, and -3 towers to have 5 darkness towers and 6 aethers.
I found out that 6 aether towers + Aether mark is just overkill and even with the auto-mulligan, the chances of not being able to rush denial someone is still high. In my way, you have a bit more choices of darkness cards with the extra mark.
Either way, an amazing deck.

EDIT: Nvm, I'm a noob.
After playing some FGs and losing, I changed back to the original because my towers were wack.
The original with aether mark is AMAZING>
Dont trust me above.
