Heartless indestructibility

Oh forgot to mention, I don't know if you have the cards already. But unless you're willing to spend a lot of money - the Godless Shrine and Isolated Chapel are crazy expensive. Guildgates are nice and cheap though.

I did not even think about bouncing Heartless Summoning back to my hand after getting the creatures out. I do like that idea! Though I purposely chose creatures with high stats to so they could stand to take a -1/-1 or even a -2/-2 hit, thus the Desecration Demons and Alms Beasts.

To take your idea into this deck, I could even think about Blood Baron of Vizkopa to complement Angelic Accord and if any Heartless Summonings are in play I could use Solemn Offering to remove and make a 4/4 at the same time.

This does kinda seem risky though. A lot of things need to be in place for those types of combos to work. The way it is set up now seems to be a bit safer to me: Have big enough creatures that a -1/-1 wont matter. I don't know, you've definitely given me some food for thought so thank you :)

As far as the duel land costs, I have the Godless Shrines but not the Isolated Chapels, though I hear they are really dropping in price the closer we get to rotation.

The card he was thinking of was Emancipation Angel. It wouldn't die when it first comes out, and it would boost your creatures to only -1/-1 instead of -2/-2. Plus, you can keep that enchantment in your hand if you feel like putting it back out to play another big creature. It's also a lower drop, so if you couldn't get out Heartless Summonings then you could at least have a defense against whatever your opponent has out already.
I would also like to recommend a tutor of some sort or another, to help you search your library for things that you'd need. Your deck, your choice. Do what you feel is right.

I hear what you are both saying and I may keep a sideboard of Emancipation Angel around to give it a shot. The one thing I am concerned of with this route is the effect on the tempo of the deck. Having the ability to play nearly any creature by turn 3 and all creatures by turn 4 and bring a 6/6 down to a 5/5 or 4/4 vs adding an extra turn to give a the creatures a +1/+1 and then possibly needing to play Heartless Summoning yet again to play a 6/8 drop creature. Both scenarios have their pros and cons.

If I were to include the Emancipation Angel what would you suggest I swap it out for?

Unfortunately the Emancipation Angel is two white mana specific - but, still it's cheap and effectively does a very similar job as an Angelic Skirmisher with a Heartless Summoning out for half the mana cost. So it's a very good card for situations where you need a cheap creature and also useful for bumping up all creatures in a late game scenario.

Also, I can see where the below chap is coming from. Angelic Wall is in there I guess to act as cheap fodder in the initial stages but has almost no purpose if drawn at a late stage of the game. I wonder if there are other ways of upping defence with non-creature related enchants and the wonderful Sphere of Safety without diluting the deck with the walls.

I can think of Pacifism off the top of my head. Love that card.

edit/
Sorry, by non-creature related enchants I meant you're own creatures. As effectively I guess what you need is a way of delaying or stalling until you have Heartless Summoning.

Yet another very useful clarification about the Angelic Walls. I can see many reasons why they are good for this deck in the first few hands, but I did not think of the negative impact they will have if drawn later in the game.

I thought about Banisher Priests or Fiendslayer Paladins for early game but the -1/-1's have a huge negative impact on their usefulness and so do not sync very well with this deck.

I could simply swap out the 4 walls for some Emancipation Angels, a 3/3 is assuredly more useful than a 0/4. The double white is a concern as well as the negative effect on the tempo as stated earlier.

Perhaps I can do some trimming down and include some O-Rings or Pacifism like you said. I really like the idea of using an O-Ring on an early threat and then, when I have built up some defenses, use Emancipation Angel to bring the O-Ring back to be able to use it on something else as the need arises.

Either way I am going to be taking a much closer look at some alternatives. Keep those suggestions coming!

So here are the changes I am thinking of making in an I/O format:

I - 4 Pacifism (SB 4 Oblivion Ring)/ O- 4 Angelic Wall
+
I - 3 Emancipation Angel / O - Alms Beast

or

I - 4 Soul Tithe (SB 4 Oblivion Ring) / O - Angelic Wall
+
I - 3 Emancipation Angel / O - Alms Beast

EDIT: Decided on option 2

I had tried to build some decks prior to this that focused on Black removal spells and though they work, I seemed to have a lot of problems vs the fast paced Gruul\Jund decks. I found i had to use removal a lot of early creatures when I did not draw any decent creatures of my own which left me open for the bigger creatures they had by turn 4 or 5. I really do love removal spells, but this deck cant have any creatures out until turn 4 unless I have a Heartless Summoning and then I can play one by turn 3.

Since this deck focuses on defense it just seemed like a safer choice. Though I am still kinda new to deck building so I may be way off here. Either way thanks for the input!

Yeah, the biggest threat to this deck is control thus the sideboard is focused almost entirely to it. If I was to swap out for Duress, what would you take out for it?

Hmmmm good question. Go down to 3 Desecration Demons. 3 Soul Tithe. 1 Ajani. Put in 3 Duress.

I had thought about Ajani's Chosen but if I happen to have 2 Heartless Summoning's out on the field the cat tokens would die as soon as they were made.

I do like the Soul Tithe spell, it can greatly slow someone down - but, because Pacifism stays on the field it benefits Sphere of Saftey. I'd say run with Pacifism.

@Ifonly & ciaranhorrex. Again, great points and thanks for the input.
I went with Soul Tithe because of A. It can be used on any non-land permanent and B. It can really slow down the enemy if they decide to pay the cost. Pacifism can only be used on creatures and it does not help with creatures like Guttersnipe, Elite Arcanist, ect... Also, If they do sacrifice the creature, I could get Soul Tithe back and use it again with Treasury Thrull.

That being said, you are both right about Pacifism being the better choice. It will benefit Sphere of Safety as well as Ethereal Armor. If Treasury Thrull was a bigger part of this deck I may still stick with Soul Tithe. I still think Soul Tithe is the better choice for Mid-End Game, but the idea was to replace Angelic Wall and have defense for the early game. Thanks again guys. +1 to both of you.

@ifonly. I hear what you are saying about the Tutor. What would you suggest I take out to make room for it and how many?

Also, since I took out Alms Beast, Treasury Thrull is the only Multi-Color I have in the deck. Do you think I should look into Renounce the Guilds?

I hear what your saying about Shrivel. Curse of Death would be a decent card if it was a lower cost, but as it sits now it just would not give enough by the time I could drop it.
One enchantment that I was really looking into was Triumph of Cruelty. Low cost and my ability to bring out creatures fast almost made the cut. The problem was the negative impact on the tempo of the deck. There are many things that I would hope to have in play by turn 3 and it does not take effect until the next turn. I did so want it to work though.

liliana of the veil is always a great choice, but alas, I do not own any. The card is still expensive and will be rotating out in a few weeks so I must leave it out.

Thanks for the suggestions though!

Sorry but I do not understand what you mean. The only creature that does not really get a benefit from Heartless Summoning is Emancipation Angel and there are only 3 of them. That is is 1/9 of my creatures rather than 1/3.

I understand what you mean. This deck originally had a few Crypt Ghast when I first started to build it to have more mana ramp options than just Heartless Summoning. I took it out because they were not really effective without a Heartless Summoning in play already. I also had 2 Necropolis Reagent in there which I have always been wanting to put back in to help build threat if I could not get a Heartless Summoning out in the first couple of turns. Maybe I can find a spot for the Necropolis Reagent or maybe something like Lord of the Void to put in there to justify the 4 Heartless Summoning. Either that or maybe go down to 3 like you say and bring one more utility card up to 4.

I would drop the summoning down to three and add one more Treasury Thrull. Getting multiple uses of Pacifism or anything for that matter is just really good.
