Here is a returning removal spell from Core Set 2013 that had a massive play rate. This time it'll be the same story all over again. Expect every black deck to have at least one copy of Murder.
Unfortunately, it would be hard to splash for it due to the two black mana in the cost, but other than that it's simply a must-have card. Also, Murder is a bit better than the previous Limited removal bomb -- Cast Down -- since it can also destroy Legendary creatures.
