This cube can change over time, as Phyrexian Gargantua getting downshifted in Commander Masters (2023) allows the card to be Pauper legal and thus the Ninth Edition card is now legal, Phyrexian Gargantua. Similarly, Juggernaut's downshift in Dominaria Remastered (2023) allows it to be Pauper legal and thus makes the Revised edition legal, Juggernaut.
