And no, they are very different in that Sleight will not allow you to keep both cards.
This argument is meaningless with respect to Opt. Sure, Sleight doesn't let you keep both cards, but Opt
forces you to keep the second card (barring the intervention of another filter). You either draw it straight away with Opt (if you push the top card) or you leave it on top.
Sleight of Hand says "you get the best card out of your top two."
Opt says "you can take the top card, or you get (essentially) a random redraw."
Yes, Opt is better in the situations where you wanted both of the top two cards, but you don't know if you're in that situation or not until you've actually drawn the next card. So Opt is way worse in situations where you want the top card but don't want the second.

The card to compare Opt to is Preordain, and Preordain is fucking bonkers because of how much immediate action it enables.
I'm sort of with you here, but Scry 2 is
way more than twice as good as Scry 1, so the comparison kinda falls flat IMO.
Opt will go into a lot of decks that won't touch Serum Visions with a ten foot pole because of the way in which the card enables you to maintain card velocity and tempo.
That's a really, really good point. I was not considering this point at all - that there are decks that currently don't play cantrips because there wasn't one that met their use case until now.
