Tons of anti-aggro tech in this while still maintaining a super strong late game.

Resizing pouch is being tested, but it's been suprisingly good. Sometimes it whiffs, but most of the time you can smartly use it to get a card you need (starfall for 5, nature studies on 1, wrath on 2, etc.)
Silas is for nabbing any big threat that you might have trouble with otherwise. Envoy Rustwix? Yoink. 8/8 Guardian with Taunt/Divine Shield? Yoink.

Crystal Merchant is such good gas and makes for good early trades too.
