Any enters-the-battlefield abilities of the copied creature 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 creature will also work.

If Mirror Mockery’s ability creates multiple tokens (due to an effect such as the one Doubling Season creates), all such tokens will be exiled by the delayed triggered ability.

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

Notably, the token won’t be attacking.

The ability that exiles the token will trigger at end of combat no matter what happens to the original creature or to Mirror Mockery.

The token copies exactly what was printed on the original creature and nothing else (unless that permanent is copying something else or is a token; see below). It doesn’t copy whether that creature 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.
