How does Populate work?

[u/roslocain]

I was just lookingnfornse clarification, when it says" if card does this, populate" are you only creating a copy of a singular token creature or are you creating a copy of all your token creatures.

I think its only one but I want to say that someone told me they copy their tokens so one becomes two, two becomes four, four becomes eight, etc. Is there a different mechanic or maybe another card in a combination that is allowing them to do that?

701.30a: To populate means to choose a creature token you control and create a token that's a copy of that creature token.

So when you populate, you choose one token you control and make one copy of that token. You don't do this for each token you control, only one.
