The more I play the R/u deck, the more I feel it’s not a winner. It has everything you need, it’s just that it’s not able to reliably find the parts you need in time. Also, it’s just incapable of reliably winning vs mono-Black and the midrange decks tend to stomp the deck because it’s not fast enough and put enough pressure on the opponent.
There has been a R/w list going around, and I’m going to try that instead over the next week.
