Mask of Mandrake

So I took some inspiration from Roshi's recent list and I am tinkering with this. Power base might need some adjusting.
We have Chalice, EHG, Ancient, Petition, and Mandrake for card advantage, If you don't have Damara use Borderlands Waykeeper.
Ancient of the Ice Caves and Damara are the only one Chalice doesn't hit.
I really like Dichro's Ruin, and Ancient can trigger a 16 health swing if you pull it off. Devour might be better over Petition but I haven't tried it yet.
