I've heard it said that Scry 1 is equivalent to 0.5-0.75 of a drawn card; is there a similar number of card draw that Surveil 1 represents?

Edit: this link has a reddit discussion that attempts to put a number equivalence on scrying: How much is 'Scry' worth in terms of card draw?.

  • Putting things in your graveyard is usually more useful than putting it on the bottom of your library. Especially in a black deck.

  • Yes; surveil as good as if not strictly better than scry in every circumstance. I'm just looking for a number.

There isn't going to be a nice numerical value that you can assign to surveil like you can to scry because the utility of surveil depends on your deck.

If you have a deck with no graveyard interaction, surveil is pretty much identical to scry in terms of card advantage. It's arguably worse, because moving the cards to a public zone gives your opponent information about what cards you want in your hand, makes the cards vulnerable to graveyard interactions your opponents might have, and makes it slightly easier for you to deck out (all of which are pretty minor).

On the other hand, if your deck has graveyard interaction, surveil suddenly jumps in value. Discarding a card with flashback or jump-start gives you half the value you would have gotten from drawing it. Surveiling a Narcomoeba is actually significantly better than scrying or even drawing it. And a deck with undergrowth becomes more powerful with every creature dumped into the graveyard.

All this makes the 'value' of surveil significantly more variable than the value of scry, and significantly harder to analyze.

    Good answer, but surveil is not identical to scry even if you have a deck with no graveyard interaction. By taking the card out of your deck, you can later shuffle your deck without putting the card back in, e.g. if you don't want to draw lands anymore, scrying lands to the bottom and then casting a card that shuffles your library is significantly worse than surveling lands into the graveyard.

    @Allure You have a point, but not all decks search either, so it's still a deck dependent advantage. Jan 3 '19 at 1:12
  • Besides the issue you bring up, it depends on your deck because the more consistent your deck is, the less deck control you need. Regarding the rest of your answer, Flashback costs are often higher than the normal cost (although sometimes smaller), so discarding one can be less than half the value of drawing. Discarding Jump-Start doesn't give any card advantage (unless combined with Madness). Putting a card with Jump-Start in your graveyard is somewhat like getting another Surveil: if you don't like a card, you can discard it to get a different one. Jan 2 at 5:55
