This is a lot like the earth/poison stall I made for the war. You're on the right track for one. If I were you, I'd remove the bone pillars. fuel the poison with a mark, put in 1-3 arsenics (if you have them), take out the hammers and a shield, then put in a couple stone pillars and enchant artifacts. You could also get rid of the dragons for stone skins.
Here's the deck I mentioned:
52o 52o 52o 52o 52o 52o 52q 52q 58o 58o 58o 58o 58o 58o 58o 58o 58o 58s 58s 592 592 592 594 594 594 594 595 595 595 595 595 595
Have fun :-p If you don't have the arsenics, the hammers or dragons would be fine.
