Whenever one or more tokens enter the battlefield under your opponents' control, for each of them, create a tapped token that's a copy of it. This ability triggers only once each turn.
Whenever one or more tokens enter the battlefield under your control, each opponent loses 1 life and you gain 1 life.

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.

Each of the new tokens copies the original characteristics of the appropriate token as stated by the effect that created that token and nothing else (unless that creature is copying something else; see below). It doesn’t copy whether the opponent’s 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.

If the copied token has {X} in its mana cost, X is 0. (Most tokens don’t have a mana cost unless they’re copying something else.)

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