as i haven't tried the deck my comments might be a bit off,
but i'll give it a go anyways
As stated above, remove the graboids/reverse time and switch your mark to
It seems that you are going for heavy quantum denial, so you want those earthquakes a.s.a.p.
Then deny them even more with the devourers and steal any pillars/permanents they got out, correct me if im wrong.
+ you need some damage (gargoyles & dragons)
To get all this fast & balanced i suggest the following changes:
Get it down to 30 cards
remove your reverse time, graboids and your stone pillars
change mark to
+ 2 Earthquakes (brings you to 6)
+ 5 Darkness pendulums
+ 6 Gargoyles (with stone form its a 5/23)
- 4 Darkness pillar
- 3 Steals
which brings you to:
593 593 593 593 593 593 5uk 5uk 5uk 5uk 5um 5um 5um 5um 5um 5um 5up 5up 5up 5uv 5uv 5uv 5uv 5uv 5uv 606 606 606 606 606
If you would like to go for a bit slower but more EM like technique then you might want to do - one pendulum - one steal + 2 Liquid shadow (cast one the stone form gargoyle -> 23 turns +5 health)
hope it helped
