Some of the key cards that really make the deck shine, we'll start here with creatures:
Mirkwood Bats: This card really makes the deck hum. So many of our pieces will ETB to make tokens which pings the table for 1. Our ends step squirrels are good for 2 damage to each opponent. Sacrificing any of our tokens regardless of type will also do more damage, so the value on this individual card is incredible.
Dimir House Guard: This is in the deck to tutor up Mirkwood Bats 100% of the time, unless you already have it. In that case you can also grab Falkenrath Noble or Chain Devil/Slum Reaper if you need an edict.
Nadier's Nightblade: Not quite as effective as Mirkwood Bats, but this triggers on any token's LTB, and we'll be seeing plenty of those over a game.
Falkenrath Noble: Not as effective as the other cards with this effect due to only pinging one player at a time, but this is the only effect that triggers on ANY creature, not just our own.
Cauldron Familiar: Seemingly innocuous, this little cat can provide a ton of value. There are plenty of ways to make Food tokens, so sacrificing them to bring the cat back and get the incidental drain is pretty big. There's also a game ending combo with this little cutie.
Gray Merchant of Asphodel: Another one of our finishers, this can sometimes be the card that levels the field, hitting multiple enemies for a few damage but gaining 3x that much back. We have ways to recur this and some other tricks we'll talk about in a bit.
Drey Keeper: A card I completely overlooked when thinking of subthemes present in the deck. This is a high end curve creature that makes us two squirrels, but in conjuction with all of the squirrels we should be making with our background, it's secondary ability really shines. Being able to pump a team of squirrels and give them menace at the same time can get us those last points of damage when we need them!
Quirion Ranger: This was a card myself and others had conversations about and I originally didn't think it was worth the addition, however I have been convinced otherwise. For the low cost of bouncing a forest, you can untap Sivriss and activate again, even on other player's turns.
Now for our supporting spells:
Unearth, Urborg Repossession, Revive the Shire, Disturbed Burial, Grim Harvest and Dread Return are all spells that can recur various card types and will bring back key pieces when we need them. Add to this Tortured Existence and Blood Fountain along with both Mortuary Mire and Witch's Cottage for a comprehensive recursion package.
When it comes to removal, we have Feed the Swarm, Snuff Out, Echoing Decay, and Go for the Throat which don't require further investment, or we have Vicious Offering, Candy Grapple, or Final Flourish that are modal removal spells that grow if we sacrifice creatures/artifacts/tokens to them. This package will remove the biggest threats in the format at instant speed.
If we need mass removal, there's Drown in Sorrow, Suffocating Fumes or Crypt Rats. Echoing Decay also hits all of the same type of token, so you can remove a board full of Gut Skeletons, TPI Soldiers or other densities of tokens.
The rest of our spells focus on protecting our commander or key creatures, with spells like Feign Death or Not Dead After All returning our killed creature to the battlefield. Otherwise we're on several spells that will sacrifice a creature while drawing us cards, like Deadly Dispute or Village Rites.
Wolf's Quarry is a card I had been considering for a while. It is a bit expensive to cast, but produces 3 token bodies and as those die or are sacrificed we also get food tokens. This means it's 6 mana for 6 tokens, and we can use those well between Sivriss and other sac outlets that provide card advantage. Bonus: with Mirkwood Bats on the field, this is 12 damage provided we have a sacrifice outlet! It's 6 damage between either Nadier's Nightblade or Falkenrath Noble.
Gruesome Fate is another finisher in this list. This spell is essentially another Grey Merchant, but without the life gain. Having 5+ creatures is easy to manage and can end the game outright.
