Hogaak is the card with by far the coolest design in all of the Modern Horizons. It relies solely on your creatures and graveyard, which means that you can run it in manaless lists, such as Dredge.
There is one tricky part though. Players to have at least two green or black creatures on board to be able to cast Hogaak through Convoke ability, since Delve can't use colors the way Convoke does.
But even then, it is very much possible to cast Hogaak on turn two or three if you have the right circumstances. It is as powerful as it can get in Modern.
