Grindy matchups are usually good:
- BGx(Abzan, Jund), URx(Grixis, Jeskai, Twin variants)
Really, they are the reason we are playing this deck.
Good sideboard options: Outpost Siege, Blood Moon, Leyline of Sanctity, Celestial Purge etc.
Usually board out some sisters, Legion Loyalist (except Abzan), some number of Lightning Bolts.
Linear aggros are usually a race:
- Burn, Zoo, Affinity, Infect, Bogles
Good sideboard options: Spellskite, extra Bolt/Path/Lightning Helix, Wear // Tear, Patrician's Scorn, Stony Silence. Basically more removals. I think Blood Moon can be good vs Infect.
I board out the 2 Purphoros, God of the Forges that are too slow. Boros Charm does almost nothing. I was boarding out Genesis Chamber vs Affinity, but not sure.
Mulligan aggressively, you don't have time to punt.
Combos are also usually a race:
Whatever you have, know their sideboard plan. They have answers against popular hate cards so really think ahead.
e.g. Ad Nauseam has Patrician's Scorn, Open the Vaults has Echoing Truth.
"Go wide" creature decks:
- Abzan Company, Elves, Merfolk, Soul sisters, (Allies, Slivers)
Removals, removals. Similar to linear aggro. Brave the Elements.
Lands decks:
- Tron, Amulet, Scapeshift
Hate their lands and protection from their sweepers. Tip: Against Scapeshift, get to 36 life.

Another use for Brave the Elements is that it can protect from targeted exile effects, namely Path to Exile which hurts far more than having our cards hit the yard, because at least then we have a chance to recur them with Return to the Ranks. Boros Charm is definitely more versatile and likely to be better in most cases, but if your meta runs a lot of Path effects, it could be beneficial. Maybe in the SB to swap with your Charms in those matchups.
Edit: Brave the Elements also protects against Dismember

I've been trying to build more of a Combo and Graveyard based strategy; namely flipping my library upside down (often repeatedly, if you have Eldrazi Titans or Gaea's Blessing, or similar) for hordes of zombies into a Dread Return into Craterhoof Behemoth. The Cephalid Illusionist + Any 0 Equip cost mentioned earlier works well for this. To my knowledge only 3 such equipment cards exist, Lightning Greaves, Shuko, and Umbral Mantle, and I think a case can be made to include all of them. Lightning Greaves is solid in it's own right, Shuko is definitely the weakest, but can easily be tutored for via Trinket Mage, and Umbral Mantle can go infinite with Krosan Restorer or Viridian Joiner (Who would also produce infinite green mana) as a two-piece Basalt Monolith to be used in conjunction with Mesmeric Orb, and additionally a milling win-con with Altar of Dementia since Umbral Mantle will pump the creatures as well.
Another notable card if you are playing mostly from your graveyard, and forgive me if it's been mentioned already, would be Body Double as it can be any one of your combo creatures if they've been dumped. Additionally any "Return target artifact from graveyard to hand/battlefield" cards are good here as well if you mill away a key card, especially if they have a body as at worst case they can function as zombie fuel. Myr Retriever comes to mind.
One of the things I like about Sidisi, Brood Tyrant is that she doesn't seem too threatening at first, and while she's assembling the combo/win she provides blockers. Round out the deck with a tidy removal/control suite and I think she could be quite fun to play.
Anyways this is my current approach for building her; can't wait to see what other lists start showing up and what other cards we'll get from Khans.
