New cards aren't always better and this is a key example of that. It's a Murder with a Cry of Contrition attached, yet it's worse than both somehow. Murder is faster and Cry of Contrition happens twice. Also, even when combined, both of those cards are cheaper. It might be good in draft (in fact, it can really hurt in draft depending on what your opponent has) but it's unplayable outside of that. It does do what it's supposed to do, but it costs too much to be worth it.
Pros: Kills a creature with no restrictions, card discard
Cons: Costs way too much, slow
