I really realy like Basilica Bell Haunt in this deck - awesome stabilizer card, especially in a meta of 3/Xs.

Same comment, it's all about syphoning off resources one play at a time.

Dance should be a 2-of in my opinion since it's really an 8-drop in this deck. You have plenty of ways to win the game if you can't find it. It is an x drop and pretty great at 6cmc. If you want 3, I'd cut a thought erasure.

The main goal is making sure you keep ahead of your opponent on resources.

Castle Vantress got cut despire it being pretty spicy tech. There will be games where you desperately need to play Kaya's wrath on t4, and the last thing you want that game is an island. The deck is now base orzhov with a blue splash - you'll notice that all of your lands make either white or black mana, at least.

She would have been fun, but I had to cut Narset from the side with this change. I think 1UU t3 followed by WWBB t4 is just too difficult with the lands currently available.

I didn't think so at first, but Liliana is really good here. the -4 is devestating when you've already been keeping their resources down.

I do wonder though if Ugin fills a similar role? It's nice that it doesn't die to color-hate, and it makes your 2cmc artifacts free.

Should you just be playing conclave tribunal over True Love's Kiss and / or Prison Realm?

I like that you can dance the enchantment back, but that means that it was in your graveyard... You don't want to release whatever your opponent had under there, especially if it has an ETB, by sacrificing these enchantments.
