While its plenty powerful, its the effect on perceived barrier-to-entry that really posed a problem because casual players watching Commander games in passing could reasonably assume that they needed hundreds (now thousands) of dollars in Power-9 mana as table stakes, just to join the format
Were talking near or over $100 through most online retailers, which is stupidly expensive for any Commander precon that still expects me to play Game Trail for untapped mana
If you use Terra as your commander, you have access to constant reanimation but only for creatures of a certain mana value (and Celes can only set up your graveyard)

Costing just three ink - with the option to add it to your inkwell instead - Cheshire Cat, Not All There focuses entirely on questing, with zero strength but two precious lore points every time you quest
I would suggest running at least 3 cards for protection in that case so that they wont reach an unaffordable mana cost from removal(s)
