Sapphire has two key cards that act as payoffs for your extra ink: Belle, Strange but Special and Hades, Infernal Schemer
These cards are never worth dismissing out of hand because it's always possible that they could be good enough to see play if the meta calls for them
By paying one colorless mana, you can sacrifice the card to give another creature you control indestructible and put all of Zacks counters, along with an Equipment, on that other creature
From the Commander format where this is an all-star adjunct but not leader to the other formats, this is pretty good to go, Idaho
Here are the offerings for the Final Fantasy set, although they appear to be selling quickly, so be sure to check both Amazon and HMV to see what's in stock and available to buy
At every playtest of the decks, I would get feedback about coworkers favorite characters, story moments, etc
