Felhide Spiritbinder — ruling 1

If an inspired ability triggers during your untap step, the ability will be put on the stack at the beginning of your upkeep. If the ability creates one or more token creatures, those creatures won’t be able to attack that turn (unless they gain haste).

Felhide Spiritbinder — ruling 2

Inspired abilities don’t trigger when the creature enters the battlefield.

Felhide Spiritbinder — ruling 3

The token copies exactly what was printed on the original creature (except that the copy is also an enchantment) and nothing else (unless that permanent 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.

Felhide Spiritbinder — ruling 4

If the copied creature has {X} in its mana cost, X is considered to be zero.

Felhide Spiritbinder — ruling 5

If the copied creature is copying something else (for example, if the copied creature is a Clone), then the token enters the battlefield as whatever that creature copied.

Felhide Spiritbinder — ruling 6

If the copied creature is a token, the token created by Felhide Spiritbinder copies the original characteristics of that token as stated by the effect that put the token onto the battlefield.

Felhide Spiritbinder — ruling 7

Any enters-the-battlefield abilities of the copied creature will trigger when the token enters the battlefield. Any “as [this permanent] enters the battlefield” or “[this permanent] enters the battlefield with” abilities of the copied creature will also work.

Felhide Spiritbinder — ruling 8

If another creature becomes or enters the battlefield as a copy of the token, that creature won’t have haste and you won’t exile it. However, if Felhide Spiritbinder creates multiple tokens due to a replacement effect (like the one Doubling Season creates), each of those tokens will have haste and you’ll exile each of them.
