I don't think it would cost you your friends. In every other game there is a clear winner and everyone else is a loser. But with a draw no one can be mad because they lost.
The best thing to do with an Enchanted Evening is to force a draw when you have Ajani's Chosen out. It creates an infinite loop that, when unanswered, lets the game end on the spot. It counts as a draw but it will feel like a win. At least it did for me the one time I pulled it off.
I think you may have a different Sidisi build in mind then. This list is for amassing a zombie horde, reanimation is more of a backup plan. But I can think of Sidisi decks that want to go the reanimator-route even more. Maybe those lists suit you more, but this here is a different approach. Or am I wrong, DementedKirby?
It's an uncommon in a set that should be sold quite good because of Omniscience, Crucible of Worlds and Scapeshift reprints, so I doubt that it will cost too much.
I found Sidisi to be the better commander but Gravetide is awesome in the 99 cards. Gravetide herself is a fun commander but I think less powerful than Sidisi.
I tried her out on friday and lost to a Xenagos-pumped, trampling Grunn, the Lonely King in turn 6 or 7, right after I got Muldrotha out. With Sidisi I would've had at least a few zombies or other shenanigans to defend myself. Muldrotha is too slow for that.
Muldrotha, the Gravetide is frickin broken in Sidisi. You may think of casting the big spells from your grave but she really shines in playing small stuff like a used Expedition Map for the full circle of Cabal Coffers, Urborg, Tomb of Yawgmoth, Thespian's Stage and Deserted Temple. Sure, sometimes you get to cast big stuff and I just played a test game with her against a Nath of the Gilt-Leaf discard deck I built together with my boyfriend. And boy, he hated it so much when I casted a Rune-Scarred Demon from my graveyard to get a Cyclonic Rift and wiped his scary boardstate away that would have killed me otherwise in the next turn.
I'm glad someone sold Muldrotha to me after the Prerelease for 5€. At the moment, the price still drops but I think it is likely to explode when the EDH players realize her full potential with cards like Dream Halls etc.
Also I really like Helm of the Host and would love to play it in Sidisi but don't know what to cut :/
Final Parting seems very good for the deck. It costs 1 more than Jarad's Orders but it's easier to cast being monoB. Additionally, it lets me choose any two card types instead of specifically choosing two creatures. Meaning I can "Entomb" a creature while tutoring for something to my hand. It's definitely worth considering, whether as a replacement to Jarad's Orders (since it has the same speed) or as a replacement to something else. The swap would definitely have to be a noncreature spell.
For five mana it enables the Urborg + Filth combo. That's mostly why I thought Sidisi needs this.
Have you thought about protecting yourself with Glacial Chasm/Delaying Shield + Solemnity? Solemnity also works well with Arixmethes, Slumbering Isle (if you got him from the precon).
Also a great card: Eidolon of Countless Battles. Doesn't even need that many Auras to be good.
Nylea's Colossus + Thassa, God of the Sea + Hydra Omnivore makes for good finishing combos as well.
And the obligatory Nyx-Fleece Ram shouldn't be left out. Everyone should have a sheep!
Entreat the Dead, Myth Unbound and Forge of Heroes sound interesting.

Archon of Valor's Reach seems fun, too, if you make some copies of it
Bountiful Promenade should also be an auto-include.
And then there is Grothama, All-Devouring. A way for us to draw many cards for some of our tokens, though I think Greater Good is still better.

In my build I will probably cut Reliquary Tower for Dryad Arbor, Ramunap Excavator for Muldrotha, the Gravetide and Jarad's Orders for Final Parting.
Unfortunately I don't know when I'm going to play this deck the next time. Probably after the Dominaria Prerelease.

I'm interested in what I have missed.
