Clone

You can choose not to copy anything. In that case, Clone enters as a 0/0 Shapeshifter creature, and is probably put into the graveyard immediately.

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

Clone copies exactly what was printed on the original creature and nothing else (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 Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, or so on.
