Magic The Gatherings Final Fantasy set in June set new records for the franchise , and given the popularity of Commander, wed imagine plenty of the four decks included in the set were shifted
So while you cant ink them from your hand, Great Stone Dragon lets you do it from the discard and bypasses the usual rulings
FCA cards are legal in Commander, Legacy, and Vintage, and each card is also legal in any other format where its already legal (e.g., Lightning Bolt is Modern-legal)
They are never readied at the start of the turn and remain horizontal throughout the game
I also want to point out that theres a treatment which isnt on this list: EA versions of the original art for the 8 face commanders, which can only be opened in the bundles that comes with two legendary EA cards, and the Collector Booster Sample packs
These cards are only one ink and can still be played in the Ruby/Sapphire deck with Belle and Beast: Maurice Unconventional Inventor Ruby When you play this character, you may banish chosen item of yours to draw a card
