This is an interesting deck, it’s Thijs Discardlock w Silverware Golem 
Darkshire Librarian. The new card Silverware Golem is used in this deck and synergies with several other cards that utilize the discard mechanic.
It’s a risk and reward deck. Don’t be surprised to lose a few due to bad RNG on the discards. But also, don’t be surprised to win games when it goes well for you. It’s a fun list though, I’ve played a few games with this deck and it’s solid enough to have a positive win ratio.
