It seems less good because Raise Dead, Disfigure and pay a life for a card are all one mana abilities and because they cover less of a range than the other Confluences

Playtest Cards This next stretch of cards, on the other hand, is both aesthetically jarring and is generally explicitly stuff that hasnt been greenlit for any kind of competitive play, not to mention that most players wont have much knowledge of every playtest card printed in a Mystery Booster release
You should include more of it in your casual builds
