When Thousand Moons Smithy enters, create a white Gnome Soldier artifact creature token with "This token's power and toughness are each equal to the number of artifacts and/or creatures you control."
At the beginning of your first main phase, you may tap five untapped artifacts and/or creatures you control. If you do, transform Thousand Moons Smithy.

The Gnome Soldier's ability will count the Gnome Soldier itself, so it will be at least 1/1.

Barracks of the Thousand's triggered ability will resolve before the spell that caused it to trigger.
(10/11/2023)
The power and toughness of the Gnome Soldier token will change as the number of artifacts and/or creatures you control changes.
(10/11/2023)
An artifact creature you control counts only once towards the Gnome Soldier's power and toughness.
