Can multiple units perform standard moves simultaneously given that rule 141.3 allows simultaneous unit movement but rule 303.2 states game actions cannot be performed simultaneously?

Ruling: Moving multiple units simultaneously is treated as one single game action, not multiple separate game actions. This allows rule 141.3 and 303.2 to coexist without contradiction.

Nuances:

• The wording may be unclear or inconsistent in the rules as written
• Questions remain about how this interpretation affects card interactions (like Merchant triggers) and whether other movement effects (like Tideturner's swap) follow the same principle
• This appears to be an exception where the specific rule (141.3) overrides the general prohibition (303.2)
