Description of the cards:
Lands could of course be fine tuned, and I haven't done testing with the deck to know how the landbase should be different. I do however feel like the 4 of confluence is a given, as they are most often strictly better than the painlands as many of the spells don't have colorless in the mana cost anyway.
Fleecemane Lion and Rakshasa Deathdealer: Feels obvious as they're very powerful 2 drops, nothing has changed there since DTK.
Boon Satyr: Good post wrath play, good surprise damage, but this could be something else. Needs more testing.
Anafenza the Foremost: A 4 of solely because I'm expecting the return of whip due to the new Sidisi. Would otherwise be 3.
Siege Rhino: Roast is a card, but so is the rhinoceros. Obvious 4 of still.
Wingmate Roc: Previously mentioned Roast is the reason I believe this card is the go to 5 drop. I'm considering Whisperwood Elementals in this cards place.
Abzan Charm: A versatile card, but hard to say how many of this I want.
Bile Blight: I do believe this is a very important card to have some of in the main, as decks this is excellent against are many.
Dromoka's Command: A fight ability that clearly needs creatures on the board, thus I think a 2 of is the correct amount.
Hero's Downfall: Most versatile removal, and I've felt very confident in the 4 of in main being a correct choice.
Sorin, Solemn Visitor: A very powerful planeswalker. Could go with 1/1 main/side, but I like the two in main against a lot of decks.
Sideboard:
Archfiend of Depravity: A card that's excellent against the GW devotion deck, and is there mostly for that one matchup.
Back to Nature: Very good card, MVP against a alot of decks.
Bile Blight: Very good against a lot of decks, especially now that Drown in Sorrow has become worse with the dash mechanic.
Drown in Sorrow: Good against quite alot of decks, even GW devotion.
Elspeth, Sun's Champion: Powerful card against slower decks.
Glare of Heresy: Answers a lot of cards, clearly want some amount of this in any white deck.
Nissa, Worldwaker: Very good against Ugin and Perilous Vault decks.
Thoughtseize: Powerful card to bring in against control and devotion.
