Mindlink Mech copies exactly what was printed on the original creature (unless that creature is copying something else or is a token; see below), except that it also has Mindlink Mech's types and is 4/3. It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or any Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, or so on.
