You went over the 30 cards quite a bit, and the pillar and shrieker amount is huge. In a backed rush or a half rush I wouldn't go over the 32/33 cards. The rest is right. Your single backup cards do not fit into that deck. A rush is no healer stall. How will you save some quantas if you ever draw the stone skin?
I would make it way simpler than this. 13/15 pillars, graboids and 4/6 golems. You still have some room for shields/BB/rewinds. I think enchant artifact is often redundant, but you can use 1 or 2. If you're counting on any card, I wouldn't put a single one in a deck. Can take quite a while to draw....
The pulverizer works better with mark of gravity, then you ditch the graboids. Totally different deck. Golems are good, but you will be slower.
Stone skin really works best if you defend heavily and do not attack. When you obtain the 75
you can lay down your best units and heal yourself a few times. In a rush it can only be a mediocre card, since usually you will not have any quanta. I found that a deck with ''time mark+CC/earthcontrol/dragons/shields'' will do to stall, as well as the ''gravity mark /pulvy/earthcontrol/dragons/shields.'' Earthquake and reverse time is excellent to stall, earthquake and pulvy or gravity force also. Many variations are possible. If you have 75 quanta anyway the dragons are a nice touch, and not many people can stop them.
