It is certainly not bad, but there is no guarantee that I can get value out of it early game. I don't have a threat-heavy list, so all of their removal is pretty free to hit the creature that it would be equipped to - and if it doesn't get value I take quite a few hits to my tempo. That being said, it is likely better than Cuombajj Witches in the sideboard, so that's a pretty strong change.
