I was playing around with
Milling wins with Feln, and it was a lot of fun, so of course I had to ruin it.
The biggest change I made was adding weapons to the deck.
Socrato, Furyheart is a lot of fun, but he was usually a 1-cost mill 7 spell. I kept the recursion to make it worthwhile to still play him that way, but I like him sticking around as a blocker and milling 7 every turn, especially if he has lifesteal.
I moved
Kindo Shadowstep to the market because I want to go all in on Socrato, but he's still fun and useful. Playing both the primal and shadow merchants, because you need
Tome of Horrors pretty badly. I'm sure you
can win without it, but let's be real. You won't.
