Versatile Golgari

So what's the goal of the deck? It seems to be exploring a bunch of different paths but not really doing anything too spooky on any front. Your curve tells me you're not aiming to go super-late, but you also don't have enough threats to rush a midrange deck imo.

Specifics:
- I think you need at least 25 or 26 lands; your deck has a lot of mana sinks and I'm assuming you want to consistently drop Reaper on turn 4. Courser should be considered as well!
- Maindecking Reclamation Sage, Return to Earth, and (maybe) Erebos is probably a mistake, those cards are 100% board. Heir of the Wilds perhaps?
- On that same note, Ferocious seems like a very relevant keyword for this deck, given that there are 6 four toughness creatures and you can make Rakshasa Deathdealer a 4/4 easily.
- Consider adding blue for Sultai. Having a graveyard deck without Sidisi just seems like a mistake, and the charm gives you great options for what the deck wants to do. You can access the delve draw spells, which will let you get rid of lands and undesirables so that it's easier to hit with Tasigur.
- Consider Abzan as well. There's a lot of self-harm in this deck and not a lot of ways to gain life other than the two god artifacts, siege rhino solves that problem easily, especially since whip is involved. Maybe up the Whip count to 2 or 3?
- I definitely have looked twice at Sudden Reclamation, I'd normally consider Satyr Wayfinder to be the best graveyard filler because he also provides a body, but I haven't played enough Sudden Reclamation to know for sure.

I'd narrow down the scope of the deck a bit, as it stands now it looks okay but it's gonna have a bad time against focused decks.

Looking forward to seeing where it goes!
