Muddle, the Ever-Changing — ruling 1

While Muddle is a copy of something else, it won't have its own triggered ability. However, if Muddle still has abilities on the stack waiting to resolve, they will do so. (It won't get multiple instances of myriad this way.)

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

Muddle, the Ever-Changing — ruling 5

You choose whether each token is attacking the player or a planeswalker they control as the token is created. If it's attacking a planeswalker, you choose which one. You can't have any of the tokens attack a battle.

Muddle, the Ever-Changing — ruling 6

The tokens created by a single instance of myriad all enter at the same time.

Muddle, the Ever-Changing — ruling 7

Any "enters" abilities of the copied creature will trigger when the tokens enter. Any "as [this creature] enters" or "[this creature] enters with" abilities of the copied creature will also work.

Muddle, the Ever-Changing — ruling 8

If an instance of myriad creates more than one token for any given player (due to an effect such as the one Doubling Season creates), you may choose separately for each token whether it's attacking the player or a planeswalker they control.

Muddle, the Ever-Changing : règles, fonctionnement et interactions (MTG)

Muddle, the Ever-Changing is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Whenever you cast an instant or sorcery spell, Muddle becomes a copy of up to one target nonlegendary creature you control until end of turn, except it has myriad. (Whenever it attacks, for each opponent other than defending player, you may create a token copy that's tapped and attacking that player or a planeswalker they control. Exile the tokens at end of combat.)

Except for the listed exception, Muddle copies exactly what was printed on the target 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.

Although the tokens enter attacking, they were never declared as attackers. Abilities that trigger whenever a creature attacks won't trigger, including the myriad ability of the tokens. If there are any costs to have a creature attack, those costs won't apply to the tokens.

The term "defending player" in the myriad rules (or any other ability of an attacking creature) refers to the player the creature with myriad was attacking, the controller of the planeswalker it was attacking, or the protector of the battle it was attacking at the time the ability resolves. If that creature is no longer attacking, it refers to the appropriate player based on who or what the creature was last attacking.
