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.

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.

If the enchanted creature is a token, the new token copies the characteristics of the original token as stated by the effect that put it onto the battlefield, plus it has haste.

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 enchanted creature is copying something else when the ability resolves (for example, if it's a Renegade Doppelganger), then the token enters as a copy of whatever the enchanted creature is copying, plus it has haste.

The token will not be kicked, even if the creature it's copying was.
