Unless a token is a copy of another permanent or was explicitly given a name by the effect that created it, its name is the subtypes it was given when it was created plus the word "Token." For example, the 0/1 green Plant creature token created by Audience with Trostani is named "Plant Token."

To determine the number of differently named creature tokens you control, count each creature token you control once, but only if its English name isn't exactly the same as another creature token you've already counted this way.
