Helm of the Host

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

The token gains haste indefinitely, and this effect isn't copiable. If something else copies the token later, that copy won't have haste.

The token 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, and so on.
