The pair of walls that sac walls to draw cards are less busted (but compared to a two mana 4/4 that cantrips being less busted is not saying much) but surprisingly important
Among all the new catch-up ramp cards in white, Id say that this card is one of the best
It seems like the kind of card that would be easy to mess up summoningafter all, it requires exactly three DARK type monsters in the graveyard to summon
