Skullclamp Suggested Cut : Dawn of Hope While Dawn of Hope works with the themes of your deck, its just too slow for my liking
As far as interaction goes, theres Ultimate Nullification and Nova Flame as tweaks to existing, top-tier board wipes (Farewell and Chandra's Ignition, respectively)
This deck seems like it might go well alongside the Bedecked Brokers Commander precon from Streets of New Capenna , based on its description
While resolving Fandaniel's second ability, the next opponent in turn order chooses up to one nontoken creature to be sacrificed, then each other opponent in turn order does the same
Command Tower, Cavern of Souls, Exotic Orchard, Path of Ancestry, Unclaimed Territory, and Three Tree City made the cut
