Surprisingly pretty good won most of the test games so far

Sites are more important for the opening hand

The main thing I want to do is play a site that is very hard to attack like The Void, Gnome Hollows or even Sinkhole Turn 1 then playing a Cornerstone close to whatever location Harbinger gives in a corner. Let them attack those sites away from avatar. Maybe a few more turns of safety

Rift Valley can work similarly I think to help keep attackable sites away

Besides that deck is huge use Hemogoblet to farm mana or feed Squirming Mass Can even be used to sacrifice someone holding Blade of Thorns extra mana and potential to use the sword again

Draw spells only pretty much
