Elven Chorus
Enchantment
You may look at the top card of your library any time.
You may cast creature spells from the top of your library.
Creatures you control have "
: Add one mana of any color."
"A Elbereth Gilthoniel, silivren penna míriel o menel aglar elenath!"

If the top card of your library changes while you're casting a spell, playing a land, or activating an ability, you can't look at the new top card until you finish doing so. This means that if you cast a spell from the top of your library, you can't look at the next one until you're done paying for that spell.

You'll still pay all costs for the spell, including additional costs. You may also pay alternative costs if any are available.
(wotc • 2023-06-16)
The top card of your library isn't in your hand, so you can't take other actions that would normally be allowed from your hand, such as discarding it due to an effect or activating a cycling ability.
(wotc • 2023-06-16)
You can look at the top card of your library whenever you want (with one restriction; see below), even if you don't have priority. This action doesn't use the stack. Knowing what that card is becomes part of the information you have access to, just like you can look at the cards in your hand.
(wotc • 2023-06-16)
Elven Chorus doesn't change when you can cast creature spells. Normally, this means during your main phase when the stack is empty, although flash may change this.
