It draws you cards and makes tokens, all while being a Zombie itself for synergy reasons
The one thing I will note: you want to be playing around 27 lands with eight cycling duals, which limits you to Grixis or Esper instead of the traditional Temur or Jeskai

Kird Ape, Serendib Efreet, and Erhnam Djinn pack quite a punch for their mana cost when compared to the rest of the card pool in 1994
This includes many zero mana artifacts such as Jeweled Lotus and Lotus Petal, as well as spells with free alternate costs such as Deflecting Swat and Fierce Guardianship, since they do not require mana to cast when the criterion to cast them for free is met
In a competitive context, Helga is a Food Chain outlet with exactly Misthollow Griffin, and in Bant that's a combo you can pretty readily find, especially if Helga is chaining some nearly free Affinity for Artifacts creatures together
