Hama the Bloodbender CEDH viability.

{"ops":[{"insert":"Hi folks. I've brewed a cedh deck with the commander of Hama the Bloodbender. "},{"insert":{"card-link":"Hama, the Bloodbender"}},{"insert":" My idea is to play a midrange style and let graveyards fill up naturally. Then, use other people's tutors or game ending cards in combination with my own to finish the game. Additionally, a potential combo that I've created is Hama + Displacer Kitten + any ritual or lotus petal in an opponent's graveyard. This results in infinite storm, infinite mana (of their ritual's colors) and subsequently infinite casts of the rest of the noncreature cards in their graveyards. I'm running this with a generic dimir cedh shell and roughly 9 other ways to clone or flicker Hama for more value. I'm wondering about the competitive viability of this?\n"}]}
