Why are so many decks not utilising this card

I honestly think so many decks are under utilising ciphermaniac, it combos so well with literally any draw card like rad ninja, Kirla, Bibarel e.c.t and like with cards such as generator , you can just guarantee that u hit every time. I get that with decks like bolt and ancient box they are locked into using sada almost every turn but like what about other decks that aren’t?
