You'll always have a full hand with this enchantment in play

Consider your goal for your readings

The major note that Id like to give about three-color Cubes is that a significantly higher volume of the cards that you draft will be castable than usual, which makes drafting mono-color and three-color decks easier than usual and also means that more playable cards will be in your sideboard than usual

I think even a single target Replenish would put serious constraints on the format and the types of designs WotC could safely make

Key cards that youd be looking at are the likes of Ethereal Armor, which gets insane with a lot of other auras, or Blazing Shoal which you can use to make a creature huge for not much mana
