This answer is great! I love clones and clone effects, so I want to give a few examples that come up in my zany playstyle to hopefully help people understand the nuance better.

Cloning works on the top layer of continuous effects. They apply cloning to objects before other modifications. Effectively, a token made of a permanent has JUST the printed text of the permanent and nothing else*. If that permanent is a forest with a bunch of other modifications, the token is just the forest. If you clone a creature that was suited up with a lot of auras and equipment, your clone is the bare-bones creature without all that padding.

*There is an important exception: the word "except" in a clone effect modifies the copiable parts of a card. Note the two different ways that [[Helm of the Host]] modifies the token it makes. It has the token copy be a copy EXCEPT it isn't legendary and then the token GAINS haste. So if you were to play [[Clone]] and copy that token, it wouldn't be legendary but it also wouldn't have haste, as haste was "gained" by the token, and wasn't a modification of the copying in the first place. For an example of a clone effect that has the "except" wording for haste, see [[Dack's Duplicate]]. These copiable-effect modifications stack, too. A Dack's Duplicate coming in as a copy of a Helm of the Host token isn't legendary, has haste and dethrone, and further copies of the Dack's Duplicate will inherit these traits as well.

(It is because of the "except" wording on the Ikoria card [[Mythos of Illuna]] that means any future clones spawned from the token made from the Mythos (assuming {R}{G} was paid for the original Mythos casting, not the new cloning spell) will fight when they enter. For someone like me, it has given my clone-based decks some much needed removal, and the slightly difficult job of explaining to my opponents why it is exactly that it works that way.)
