Worldwalker Helm

The new token created by Worldwaker Helm's last ability copies the original characteristics of the target token as stated by the effect that created the target token and nothing else (unless that token is copying something else; see below). It doesn't copy whether the target token is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

Any enters-the-battlefield abilities of the copied token will trigger when the token enters the battlefield. Any "as [this permanent] enters the battlefield" or "[this permanent] enters the battlefield with" abilities of the copied token will also work.

If the copied token is copying something else, then the new token enters the battlefield as whatever that token copied.
