Dimir has Surveil. Surveil seems quite good and there’s plenty of cards that have it. Many of them seem (at least without context) to have an outside chance of making it in Standard.

It’s not as if we don’t have tools ready as well. [scryfall]Search for Azcanta[/scryfall] already has Surveil 1 on it, although not having the actual text printed on it might actually matter, as some cards are triggered by using it.

For the reanimation, we have [scryfall]Connive // Concoct[/scryfall], part [scryfall]Control Magic[/scryfall], part [scryfall]Rise from the Grave[/scryfall] with Surveil pasted on it. What’s important as well is that it doesn’t target, so if opponent has a way to empty your graveyard, you may still use it if you find something to bring back. Well, at least as long as you hit with the Surveil and there’s isn’t an effect like [scryfall]Rest in Peace[/scryfall] on board.

There’s actually so many of these small Surveil creatures that I’d be a bit worried about too much consistency in the decks. It’s so easy to churn through the deck to find something specific and you also leave bodies behind (some of the time, at least), so you are not simply looking through you deck. You also have actual blockers and possibly attackers.

So, maybe the deck could look something like this:

[deck]
[creatures]
3 Lazav, the Multifarious
2 Thoughtbound Phantasm
4 Dimir Spybug
4 Blood Operative
2 Dream Eater
1 Doom Whisperer
1 Demonlord Belzenlok
2 Muldrotha, the Gravetide
2 Carnage Tyrant
[/creatures]
[spells]
2 Disinformation Campaign
4 Connive // Concoct
2 Enchanced Surveillance
2 Price of Fame
4 Thought Erasure
2 Sinister Sabotage
[/spells]
[lands]
4 Overgrown Tomb
4 Watery Grave
4 Woodland Cemetery
4 Drowned Catacomb
1 Forest
3 Island
3 Swamp
[/lands]
[/deck]

Admittedly, the targets for reanimation are not very good, but there are bigger green things available as well. In fact, currently, the major bonus from the renimation is the ability to bin the big things, which you don’t want to draw early, and use them later.

(Don’t trust the manabase, it’s a “work in progress”.)
