This is a pretty solid take on the Vampires decks, and a lot of fun. The Mardu package make it very good on the removal side, with the main star being Rite of Oblivion. Since you can use it twice, it goes a long way for you. There are a lot of micro interactions in this deck that can get the opponent by surprise, and no game feels unnwinabel when piloting this. I found the Orzhov and B versions very underwhelmin compared to this one. Took it to Diamond 1, but I feel it can go higher than that.
