Though both are better than Gnarled Mass itself
Dennick, Pious Apparition helps keep the cards flowing by letting you Investigate whenever one or more Creature cards are put into graveyards from anywhere, which means normal gameplay actions like trades in combat, removal, milling, self-mill, all of it, can quietly keep feeding you Clues and making sure you don't ever run out of gas
I also like this in creature heavy midrange/blink that is playing things like Ravenous Chupacabra, Liliana's Specter and Mulldrifter and similar things all over the place for its spell slots
For better or worse, advertising seems to work wonders on me
