Survival made this thing broken in Standard with this getting discarded over and over and over and over again and never got, you know, played
A counter generator that has a TON of extra value strapped to it is absolutely nothing to scoff at though, and the reanimation can be super strong if you can time it well
While I think it's a little worse than something like Oath of Nissa, this is easily the best version of a "Commune with" card since it can hit all creatures, as opposed to something like just Dinosaurs and lands or something
Similar to Champion of Wits, Hour of Promise will most likely see the most play that it will while Ulamog, the Ceaseless Hunger is still in the format, but I also think that we are just scratching the surface on how good this card can be
But if you just want to make a version of your favorite commander with an image of your pet or something similarly sentimental, or you want to see your idea for a custom card come to life, card makers are just what you need
