Splinter Twin

If the enchanted creature is legendary, you will have to put either the original creature or the token into the graveyard as a state-based action.

The token that's put onto the battlefield copies exactly what's printed on the enchanted creature (unless that creature is copying something else or it's a token; see below), plus it has haste. It doesn't copy whether the enchanted creature is tapped or untapped, whether it has any counters on it or Auras attached to it, or whether it's been affected by any noncopy effects that changed its power, toughness, types, color, or so on. In particular, it doesn't copy the ability granted to the enchanted creature by Splinter Twin.

If the ability is activated during a turn's end step, the token will be exiled at the beginning of the following turn's end step.
