The Mirage design team (Bill Rose, Joel Mick, Charlie Catino, Don Felice, Howard Kahlenberg, and Elliot Segal) while working on Visions ended up creating enters-the-battlefield effects as well, but I hadn't yet seen the cards when I created Gravedigger
That adds up fast, and you could even lean into cat synergies if you felt inclined to do so
hiding and guaranteeing your board wipe is extremely valuable in a format with so many wheel effects, and three mana on a subsequent turn is a fantastic rate for such a strong spell

For just three mana, you can start getting wild with convoking very early on in the game.
I also took this opportunity to think about my own deckbuilding and how I want to build decks in the future
