Astral Dragon

If the copied permanent has {X} in its mana cost, X is considered to be 0.

If the copied permanent is a token, the new token that's created copies the original characteristics of that token, with the exceptions noted above.

Except for power, toughness, types, and the flying ability, the token copies exactly what was printed on the original permanent and nothing else (unless that permanent is copying something else or is a token; see below). It doesn't copy whether that permanent is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, and so on.
