What are tokens in Riftbound, what represents them, and what do they do?

Ruling: Token units are units created by effects that do not count as cards. They can be represented by anything players agree on (official token cards, dice, etc.), exist outside the game when not in use, and are kept off to the side (not in your deck).

Sequence:

• Tokens are created by effects as specified
• They enter the board with stats (might, etc.) as specified by the creating effect
• When tokens leave the board for any reason (killed, sent to hand, etc.), they are destroyed and vanish back to ether rather than going to trash

Nuances:

• Different token types exist (sprites have 3 might, recruits have 1 might)
• The effect creating the token specifies its might
• Tournament rules require tokens to be able to represent card state (exhausted, might, etc.)
