Morph, Space Goo Emerald is already considered one of the best colours to play if you like using Lorcanas Floodborn Shift mechanic, which is the ability to play character cards for cheaper by putting them on top of a character with the same name that you already have in play
Players can only place one card into their inkwell once per turn, so any ability that allows more ink to be accumulated, especially early in the game, is very useful
This helps with quickly ramping up the number of cards in your inkwell , making it easier to play the high cost characters like Belle, Mechanic Extraordinaire, who can also be a shift target , as well as Lyle Tiberius Rourke, Crystallized Mercenary, who is not only a key damage dealer , but also pretty darn good at questing
(Some abilities can also target unexerted cards.)
