Is there any way to turn a token into a nontoken?
Within the actual rules definition for &quot;Token&quot;, such a thing really isn't possible.


Tokens


111.1. Some effects put tokens onto the battlefield. A token is a marker used to represent any permanent that isn't represented by a card.


With this definition, something becoming a nontoken really means that the thing becomes a card. And to become a card, you need a physical real-world card to have a card in general.
So as long as something is a permanent, and it isn't represented by a card, then it is a token. The closest thing you could do is replace a token with a different non-token that does the same thing... i.e. you could have an ability that says &quot;sacrifice target Forest token. Choose a Forest card you own from outside the game and put it on the battlefield.&quot;
But if an ability said something like &quot;target token becomes a non-token&quot;, it would just be confusing... Even though effects on cards can override any rules in the rulebook; an effect like this would basically be just redefining the word &quot;token&quot; as it is in the rules. Assuming that you aren't talking about it actually becoming a card; then it becomes an entirely new thing that is a concept never thought of in the rules... a permanent that is neither a token nor a card. You would need to alter a ton of other rules to make it work... what happens when this non-token, non-card enters a graveyard? You would likely need to replace the rules that make tokens in graveyards cease to exist with a rule that applies to all non-cards in graveyards instead.
