Dies to Removal

Nah, you don't want that. A splqsh color means our mana base hurts, and most versions don't play 4 martyr anyway.

There's actually a version that splashes red for Norin the Wary and Purphoros that's put up some results.

Swarm. Pridemate is pretty much a better Goyf, and ascendant is just there because it can be very powerful in the early game.

I've seen it in lists that top 8'd MODO dailies before, but personally I don't care for the card in this deck.

Also, I've played against UWR quite often, and I've found that, against most versions, you'll want to bring in more BTEs for Paths. Many of the lists lower the creature count for more sweepers against you, so this sub makes a lot of sense.

From FNM (I know, it is FNM, correct me I'm totally wrong on this): Vs melira pod: - 4 pridemate - 2 honor +2 sundering growth +2 rest in peace +2 suppression field

To be more direct, can someone with more experience with both Sisters and the Modern format tell me what cards can be taken out in certain MUs? I feel really lost here.

Taking this to FNM tomorrow; anyone have advice on sideboarding? What are the cards that you never side out? With a deck with a very tight plan such as this one, it is sometimes difficult to see which cards will be the least important in a match. I usually take out the Martyrs against midrange and Ranger, sisters (max 2), Path, or Procession against various forms of combo, depending on the type and how many cards I want to bring in, but none of the substitutions ever feel as "clean" as the ones I make when playing a type of red aggro.

Looks pretty solid. However, you'll definitely dump your hand pretty fast, and it seems like you'll lose often to midrange. Maybe not Jund as much, but traditional midrange may be a problem. I also think that any version of this deck definitely wants a full set of Squadron Hawks; especially this one. Auriok Champion could also work well here.

Also, Kaze, do you really need 10 sisters? I only play 6. Auriok Champion is very good, but so is Aven Mindcensor.

On lands: I'm not sure that running more than 2 Windbrisk Heights is correct, as I seem to often get screwed over by them. Playing creatures the first few turns seems more important than activating Windbrisk. Also, with the changes coming to the Legend Rule next month, running multiples of Flagstones of Trokair now has absolutely no drawback, save for the fact that you have to spend white mana during the phase you play the second one. We don't really need the Landfall triggers, so I guess it's really only relevant against Smallpox. I have also found that I want 2 or more Ghost Quarters to stop Tron the moment it rears its ugly head.

Additionally, the general low-interactivity with opponents is why my version plays 4 PtEs. You really need to get that Melira/Redcap out of your face the turn that it hits.

There is a lot of combo hate in the sideboard. There are multiple cards that ensure that the opponent will not activate a Birthing Pod, reanimate a creature or sling a storm of spells at me. 3 sisters will also stop a splinter twin-type combo. Also, I have yet to face a control deck at the store that I play at, and Modern tournament season is many months away, so I doubt I'll be playing anywhere besides there. I picked the deck because my local meta is just so full of aggro decks.

Soul Sisters is the newest modern deck that I've picked up. I have yet to gain much of a feel for the deck from tournament experience, but once I do I'll write a proper primer for it. Until then, discuss!

Additionally, someone wrote a primer for this on MTGS recently. However, it is very general and seems as if the card choices section could have been written simply by looking at the cards, not even plating them. Better than I have,
though, so if you're curious, look here
