Sir Stone's Comments
Rin, the First Disciple
Now that all cards are released and there are no new cards that help this card to not make you spend 41 mana on something that will destroy what’s left of your opponents deck, shall we conclude that Rin is more valuable as dust than a minion?
Rin, the First Disciple
Even then, if your opponent has Millhouse they will for sure use it on turn 2 not like turn 7.
Hooked Reaver
Hooked Reaver will be filling in for Flamewreathed Faceless after he retires to Wild.
The Darkness
Plus you could add other cards to make your opponent draw faster like Coldlight Oracle, Naturalize, or even Dancing Swords or even Deathlord!
Sewer Crawler
Also with Brann Bronzebeard or Murmering Elemental, it would summon two 2/3 Giant Rats instead of one.
To be fair, Mass Dispel is still a thing.
