Definitely a work in progress, but I have had a lot of fun playing it all week. I played against a similar deck and liked it a ton so I decided to give my own spin on it, I'm tempted by trying out a Black Market with some useful relics (
Infinite Hourglass would probably get put in here instead of running 3 main), and I'm also considering running
Scavenge for more rats or
Be Gone as some form of interaction and to turn on
Star-Reader Severin sooner.
Vault of the Praxis I didn't consider much until now and I had never even heard of
Perilous Research until today. I'd love to hear some input if you have some ideas and I hope some others give this deck a whirl.
