Devastating Onslaught

The tokens copy exactly what was printed on the original permanent and nothing else (unless that permanent is itself copying something else; see below). They don’t copy whether that permanent is tapped or untapped, whether it has any counters on it or Auras attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on. If the permanent is a Vehicle, the copies are not crewed. If it is an Equipment, the copies are not attached to any creature.

If the copied permanent is copying something else, then the tokens enter as whatever that permanent copied.

Any enters abilities of the copied permanent will trigger when the tokens enter. Any “as [this permanent] enters” or “[this permanent] enters with” abilities of the copied permanent will also work.
