2022-10-07 : A token that’s created as a copy of another object will remain a copy of that object after it leaves the battlefield. Assuming it copied something with a mana cost, the token will still have that mana cost, so it can be cast as normal from wherever it is if you have permission to do so. Note that this is different than a token that becomes a copy of another object and then leaves the battlefield. In that case, the copy effect wears off as the token leaves the battlefield.

2022-10-07 : After Claire D’Loon’s enters-the-battlefield ability resolves, any token you own that leaves the battlefield will remain in existence in whatever zone it goes to. This means you must continue to represent that token with a physical object wherever it is. This applies to all tokens on the battlefield when the ability resolved, as well as all tokens you create for the rest of the game.

2022-10-07 : If a token under Claire’s influence ends up in your hand or library, the token needs to be indistinguishable from the other cards in that zone. If you’re using printed tokens, great! Make sure you’re matching the sleeves of the other cards in that zone, if any. If the token is represented by another object, such as a body part, a phone, a cat, some food, or a toy, use a Magic card (preferably a token) as a stand-in.

2022-10-07 : Thanks to Claire, tokens can end up in your hand. Thanks, Claire. Most tokens don’t have a mana cost (though see below), so a token that ends up in your hand can’t be cast unless you find a way to cast it without paying its mana cost.
