So i'm wondering if Red is worth it in here, or if just being straight GB is better.
Shenanigans and Faithless looting are the best red has to offer, neonate is meh, Anger is a consideration but without entomb probably not great. Putrid imp while less strong than looting has a ton of other synergies to make up for it. You need green for enchantment hate anyway, and hard casting VVines while not something that will come up often is still a thing.
My biggest question is if Rituals are worth it or not? Extra lands are good with Crawler and Bloodghast, but being explosive is valuable too.
I think i'm going to start with this and go from there, and see if i need the added power of looting is needed or not and if rituals perform at all.

Not sure how fancy you can get with the mana base. I think with Rituals you want to keep it basic. But if you cut them i would want to try out a Phyrexian Tower and maybe a Cabal Pit or 2, just for some main deck interaction.
Sideboard would probably start like this i would think:
4 Leyline
4 Assassin's trophy
as a base and then other options could be:
2 Collective Brutality
3 Thoughtseize / Hymn / Mindrake
2 ?
I've got a legacy 1k Coming up in a couple of weeks, probably give this a spin if i can get Hogaak's.
