Jaxis, the Troublemaker

The token copies exactly what was printed on the original creature and nothing else (unless it's copying a creature that's a token or that's copying something else; see below). It doesn't copy whether the creature is tapped or untapped, whether it has any counters on it or Auras and/or Equipment attached to it, or any non-copy effects that changed its power, toughness, types, color, and so on. Most notably, if the target creature isn't normally a creature, the copy won't be a creature.

You don't have to attack with the creature with blitz unless another ability says you do.

If another creature becomes a copy of, or enters the battlefield as a copy of, the token, that creature will copy the creature card the token is copying. However, it won't have either haste or "When this creature dies, draw a card," and you won't sacrifice the new copy at the beginning of the next end step.

The triggered ability that lets its controller draw a card triggers when it dies for any reason, not just when you sacrifice it during the end step.

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 card will also work.

If a copied creature is a token that isn't a copy of something else, the copy copies the original characteristics of that token as stated by the effect that created it.
