Can a player create tokens using cards from their opponent's token deck if their own deck doesn't include those tokens?

Ruling: Tokens exist outside the game and are not part of any deck. You can use any object (dice, unofficial tokens, etc.) to represent tokens you create. You may use your opponent's token cards if they agree to let you borrow them, but they are not required to provide them.

Nuances:

• Tokens don't have to be official token cards - any agreed-upon object works (dice, tokens from other games, etc.)
• You cannot take your opponent's token cards without permission
• The source of the physical token representation doesn't affect gameplay
