Wizards of the Coast brought about the Commander power brackets which take many of these rules into account and help players get good games
Celestine does require you to gain life before you can start bringing creatures back, with so many ways to efficiently gain life in Commander this isnt a problem at all
So if I make my commander Captain America, First Avenger (a red-white-blue creature), I cannot use any green or black cards while building that deck
Hes not looting away cards, which unfortunately doesnt do much for graveyard-based decks like Jace did, but the enchantment he transforms into is arguably stronger than Jaces Planeswalker side
Now that seems like a fairly easy chase in comparison to some of the steep odds to pull modern alternative arts
