No, you don't. But if the attack Metronome is copying states you must do something "in order to use this attack", you HAVE to do it EXACTLY as it is stated (like discarding a specific color of Energy).
As I remember, the wording for metronome is:
"Choose 1 of the defending's Pokemon attacks. Metronome copies that attack
except for its Energy cost and anything else required in order to use that attack,
such as discarding Energy cards. (No matter what type the defending Pokemon is, Clefairy/Clefable is still Colorless.)"
~Copied from Base Clefairy~
So correct me if I am wrong, but the old WoTC ruling states that energy costs is a requirement, as well as anything in the card text that says 'in order to", and unless PUSA has amended this ruling, it should still stand.
I remember this because it was the sole reason why Clefable was able to copy Charizard's Fire Spin without discarding two energy cards, or at least until Legendary Collection came out with the new text.
Which would also mean that if the text did not specify "in order to" on the discarding part, then yes, Metronome would still require the discarding to be done.
Or am I wrong here?
On the Holon Energy, I don't think you need both energy to use the 2nd effect. As stated, the word "also" is repeated twice, and fortunately, appears at the start of both effects' sentences. If needing both for the 2nd effect is true, then it would follow that you would also need both for the 1st effect.
In other words, the word "also" is
for cases when there are any OTHER energy of that type attached to the Pokemon, an effect OTHER than providing the Colorless energy. Or basically, it provides [C] energy and
also effects so-and-so. That's what the "also" is for.
English sucks, basically.
So rejoice, you only need one energy of that type to activate either effect.
