This is my take on a nest of scarabs deck, any advise is highly wished for!
4x Ammit Eternal:Strong 3-drop, deals a lot of damage regardless of being blocked or not, and it speeds up our token production!
2x Channeler Initiate:2-drop that creates 3 insects, becomes stronger over time and produces mana.
4x Exemplar of Strength:You only need a single insect token and you have a 4/4 2-drop that creates 3 tokens. Holy :o
2x Festering Mummy:Decent early drop and a fine combo piece for Exemplar of Strength.
4x Hapatra:Seems obvious.
4x Obelisk Spider:Same as Hapatra :p
4x Soulstinger:Now here is the thing. Soulstinger might seem a little weak, but you should not underestimate this card. You get easy tokens and a good blocker, that acts as a small removal AND creates additional tokens on his death. Just remember to always put his -1/-1 counters on himself!
4x Nest of Scarabs:Your opponent will have a phobia for insects after you play this card xD
4x Grasp of Darkness:2nd best black removal after fatal push ( i didnt use fatal push to keep the budget low)
4x Grind // Dust:This card does work. Kill aggro decks, create tokens, AND have the perfect removal for a -1/-1 deck. You'll get the white mana by Aether Hub or Channeler Initiate.
2x Aether Hub:Pretty much used for Grind // Dust aftermath, but also useful if you need Hapatra or Channeler and can't find a forest.
2x Blooming Marsh:Solid dual land.
So yeah that's the decklist. If you have experience with this type of deck or have some good ideas for cards please leave a comment!
