Try to use the deck image creator, the cards that are one after the other just up the aether picture. Copy the import code and write the mark in the designed place. It won't make people have to read through it, and it is much easier for you that way, too.
1 - As it has been said, going with the basic shrieker rush is better. The ONLY modifications that should be made to that would be - Earthquakes, Rewinds, or Basilisk Blood, so it doesn't loses considerable speed, in which it's really good at. Your version as it is now is pretty much slow.
2 - Reflective shield = Loss. The deck itself is good. How to fix the auto loss, would be mark of light, swap one or two pillars for a reflective/mirror shield of your own. ^^ I, however, know a better and - hopefully - more efficient build with darkness that also gives EM, that is the classic Liquid Shadow Dragons. Fractal Vamps is always nice, too.
3 - No real comments. Considering each dragon costs about 10 + quanta, you would only be able to play them eeeend game, which would most likely be near your death or you already died. Also, in the steam machine you are using fire quanta, which sucks up the quanta of the highest attacking critter and dragon in the whole game.
