I could think about removing Guards and adding another critter... Gargoyle can be good, but dunno if it will work. It also would need an extra Earth quanta. Need to test. GotP is expensive. I thought about it, but If I would add them, most probably just 1.
I surely wont add Hourglasses. It uses Mitosis, so usually the field gets crowdy fast. No need to use Hourglasses. And in case they are needed, they would possibly trouble the stall strategy, because the deck is supposed to overlast the opponent.
Fractal is also something I dont intend to use... but a Mind Gate or 2 could be interesting
I will think about that.
