Looks like BG is once again graveyard-matters on Innistrad. Not sure where the floor for a reasonable version of half a Spider Spawning but decayed Zombies lies, but two mana seems pretty cheap. Important to note that it's one of the rare graveyard-related Zombie token makers that doesn't exile the creature cards out of your graveyard.
You can crew Vehicles with decayed Zombies turn after turn without them rotting away, so it's nice there's Zombie making spell in the same color as Esika's Chariot. Gonna be interesting Standard season.
There's a lot of cards in Kaldheim that are almost as obnoxious as those in Eldraine - Chariot, Goldspan Dragon, Alrund's Epiphany. And both Tibalt and his Trickery, one that gets cheated onto the field and the other that cheated Emrakul in before geting banned. Power creep never dies.
