Infinite combo with Anafenza, Kin-Tree Spirit + Kitchen Finks + Viscera Seer while also just being solid cards in the deck. The rest plays like a Modern Death & Taxes deck with the Leonin Arbiter +Ghost Quarter + Path to Exile suite.
Dark Confidants for card advantage, which is very needed in this deck to find the combo. Originally was just playing 2 more sac outlets Cartel Aristocrat and 2 more enablers Murderous Redcap, but these cards were very lackluster on their own and I'd rather just be playing the optimal combo pieces along with a better way to find them.
Thalia, Guardian of Thraben because it's good for both aspects of the deck, D&T and Combo. Helps protects your creatures from removal while slowing down your opponent (works well with all the land death too). Only 3 because she's legendary. Debating dropping down to two, but I couldn't find a decent replacement and she is very good in the deck.
Flickerwisp is a staple and also can help protect with creatures from removal with addition fromAEther Vial. Usually what wins my games, whether it's from the plan B of beating down (which is actually probably the plan A) or from protecting my combo pieces. Also is often a 4/2 thanks toAnafenza, Kin-Tree Spirit, which is great for a 3 mana flyer.
Inquisition of Kozilek better than Thoughtseize considering this deck already takes a lot of damage due to Bob and the lands. Used to have the extra Thalia and 2 Restoration Angels in this card's place, but I've found the 4 cmc of resto being a bit too much. The card has been good and a 2-for-1 plenty of times, but I feel like the utility of knowing the opponent's hard and also taking away a removal spell, for the most part, is better. I never have to worry about flipping a 4 with Bob and I can know when it's okay to put my combo pieces in harm's way.
The Mana Base (What I'm Most Unsure About):
Caves of Koilos, 4 of them, because Isolated Chapel came into tapped way too often. The pain is not irrelevant, but having the one Isolated Chapel and one AEther Vial hand is too miserable. The only tapped land in this deck is Shambling Vents, but this card can gain life and gives the deck a 4 mana play. Eiganjo Castle helps protect Anafenza and Thalia, so I feel like it's better than a Plains. Ghost Quarter and Godless Shrine are definitely mandatory. Shizo, Death's Storehouse is mostly just another come into play untapped black source because this deck plays 7 black one drops and effectively no white one drops (rarely Path on turn one). 2 Tectonic Edge just because it's the 2nd best LD besides Ghost Quarter, but I could see myself removing those. Also Urborg, Tomb of Yawgmoth is just another come into play untapped black source that can turn all my colorless lands into something useful. I've definitely thought about playing with Isolated Chapels and removing the Urborg, Shizo, and Tec Edges for Swamps / Plains and also a couple of Caves, but I'm not sure if this would be a good decision or not. I feel as though the mana base would be a bit more consistent and less painful, but a lot of utility is gone.
Help on the SB is extra appreciated. So Splinter Twin and Bloom are banned now so I don't have to worry about those decks. What're some good cards against Tron and Eldrazi Control maybe?
