Here Comes a New Hero!

The token copies exactly what was printed on the original creature (unless that creature 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 any Auras or Equipment attached to it, or any non-copy effects that have changed its types, color, power and toughness, and so on.

If the copied creature is a token, the new token that's created copies the original characteristics of that token as stated by the effect that created the token.

If the copied creature has {X} in its mana cost, X is 0. This is also true when calculating the mana value of a creature on the battlefield in order to determine whether or not the creature is a legal target for this spell.

If the creature copied by the token had any "when [this creature] enters" abilities, the token also has those abilities, and they'll trigger when it's created. Similarly, any "as [this creature] enters" or "[this creature] enters with" abilities that the token has copied will also work.

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