Are custom fan-made tokens legal in competitive play?

Ruling: Custom tokens are legal according to current rules as long as they can noticeably show exhausted/ready states and differentiate between token types. However, official tournament rules have not been released yet, so competitive legality is not definitively confirmed.

Nuances:

• Current game rules allow anything to represent tokens if exhaustion can be shown
• The same principle that applies to buff counters (can use anything) is expected to apply to token units
• Tournament-specific rules may add additional restrictions when released
