The idea is to gain card advantage through Hatching Plans and Treacherous Blessing. There are cards that can sacrifice those permanents. There are other permanents that can be sacrificed for little loss if neither of those are on the battlefield.

4 Hatching Plans
4 Treacherous Blessing

4 Rite of Oblivion
4 Perilous Research
4 Abjure

4 Force of Will

3 Faerie Seer
4 Devoted Grafkeeper
2 Malevolent Hermit
3 Lingering Souls
1 Reservoir Kraken

4 Prismatic Vista
3 Flooded Strand
3 Polluted Delta
2 Underground Sea
2 Tundra
2 Scrubland
3 Marsh Flats
1 Plains
2 Island
1 Swamp

This deck could go into red for Crack the Earth, but I don't know as it is worth it. It could also go down to 2 colors.

Here are some other cards that could be included:
Baleful Strix
Gutterbones
Master of Death
Dennick, Pious Apprentice
Faithbound Judge
Katilda, Dawnhart Martyr
Chaplain of Alms
Sarcomancy
Burglar Rat
Charming Prince
Citizen’s Crowbar
Mortarpod

Are there any things I am overlooking that should be considered for the deck?

Also, I am not sure which other lands should be included. I want to be sure to have the three colors, but I feel like I could get more out of the manabase than the current set of cards.

Thanks!
