If another ability of a source you control triggers when attackers are declared, such as that of Hamlet Captain, you may have it resolve before or after that of Hanweir Garrison. If that ability has targets, it won’t be able to target the tokens.

If another ability of a source you control triggers when attackers are declared, such as that of Hamlet Captain, you may have it resolve before or after that of Hanweir, the Writhing Township. If that ability has targets, it won’t be able to target the tokens.

On the turn they enter the battlefield, the tokens are never declared as attacking creatures. They simply enter the battlefield attacking. They won’t cause any abilities that trigger “whenever a creature attacks” to trigger.

You choose which opponent or planeswalker controlled by an opponent each token is attacking as it enters the battlefield. It doesn’t have to be the same opponent or planeswalker that the trigger’s source is attacking, and the tokens don’t both have to attack the same player or planeswalker.
