You have only one source of colorless mana for your Eldrazi Displacer.

Perhaps Rhox Faithmender to make everyone double mad?

He is just to big. Everything drops on a 1 or 2 drop. With Thune backing everyone up for mid/late game action.

I snap Martyr with Ascendant combo turn two, orany number of effects to get three to trigger the Lone Rider.

As is, most every game I have a 5/5 flying life link or 6/6 flying life link by turn 4. And that's no small thing to deal with.

Droping Honor of the Pure since having Archangel of Thune makes it pointless. And as far as the inflation of spirits for a rush or for protecting my sisters from removal its just not effective anymore.

I really like Lone Rider  ^Flip. It has serious surprise factor having tramping in mono white. If it flips(which happens easily enough), you have to remove it.

Martyr proc pretty much relies on squadron hawk. You might be able to benefit from martyr otherwise but but since you drop most of your deck early game, it's practically useless if drawn after the first couple turns.

If you are relying on Squadron Hawk for Martyr of Sands, then you are taking a hyper speed deck and making it slow.

That's turn three at best to impact. Squadron is in the typical Sisters build for three reasons.

One - so that late game(turns 4 - 6) if you cast martyr you can have cards in hand to use her.

Two - so that you can increase card draw %, this is a big deal on hyper decks. Note that you would also want to run Flagstones of Trokair to totally complement this effect.

Three - since you will most likely run Honor of the Pure having 2/2s and 3/3s(which is routine) with flying and casting three is a big deal.

When running Thune, you extend your gameplay to 4-6 on the norm, but you also get nasty in long game play.

The bird isn't needed for martyr and Ranger of Eos is very effective at mimicking this effect.

Also, in this build; using Martyr with 1 card in hand procs Lone Rider. This is not ideal at all. But I try to build the deck to take advantage of each card with multiple situations in mind.

I am currently thinking of dropping down to 3 Thunes and adding something else. Not sure yet on what.

I like going down 1-2 Archangel of Thunes. I would add in a Mana Tithe for the copy of the angel. The potential with a Mana Tithe is worth a 1-2-of IMO for the times you can blow out the unsuspecting opponent or slow down the suspecting one.

Yes, Flying nuns made me make this change. So shout out to "https://en.wikipedia.org/wiki/The_Flying_Nun"

what you thought the deck? Please the movie.

The following cards only have a casting cost of 1 or 2, and may be useful?

i. Brave the Elements can facilitate a massive, sudden surprise attack. A cheaper alternative is Gods Willing.

ii. I think also Ordeal of Heliod synergizes well with the deck.

iii. Also Authority of the Consuls slows down your opponent while helping you gain life.

iv. Brave the Sands can also be useful for attack-defense.

Anyway, enjoyed your deck! +1

I have brave and its a good sidebar.

Ordeal is to slow most times or it boost life which isnt needed as much as you think.

Autority is another great 1 per deck card and I been toying with it.

Sands... I dont block unless I am chump blocking.

Can you take a look at my soul sisters deck? Ajani's Chalice of life gaining awesomeness!
