Nice deck,
I use a slight variant myself and finding it is quite succesful, using a few more pillars as to maximise the heals from stone skin
58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58q 58r 58r 58r 58s 58v 590 590 590 590 590 590 594 594
Have a lone golem to balance the pillar/monster ratio. Also being a poor man I don't have the shards.
I find the health stability useful versus various counters to shriekers. Besides at 8 vs 8dmg shriekers on their own are just as good as golems and for an extra 2 the 10hp of the dragons is pretty good. Also we use pulvy because its 5 damage, even though we cant use the ability.
