Call 021-Chalice

Deck focuses on stalling out using the existing Crystalline Chalice shell, combined with Amber Ring to smooth out bad draws. Amber Ring also provides a bunch of cheap chump blockers early on when you have power to burn each turn but not enough pieces of your drawn engine to really get going.

A lot of games are won by casting Harsh Rule onto a board full of 3/3 Explorers, dropping a Call the Ancients titan and using Mating Call to pull 2-3 more from what remains of your deck.

Eilyn's Choice deals with some large threats and prevents your opponent from casting double Harsh Rule into a board of titans.
Bring Down is really versatile and deals with problem cards like Inquisitor Makto and to some extent Icaria, the Liberator.
Kothon, the Far-Watcher is a 1-of because that's all I have at the moment. I'm never excited to play him, but I'm also never sad to see him. Still unsure what to take out if I wanted to include more.
