Coldsteel Heart Discussion

SideBae on Mono-Black Gold (Shirei, Shizo's Caretaker)

Mana Vault on turn one allows you to cast your general turn two. I imagine one of the challenges with this general is his costing 5, as lack of access to another color means your options for ramp are rather limited. By the same token, Charcoal Diamond , Coldsteel Heart , Chrome Mox and the Cabal Coffers + Urborg, Tomb of Yawgmoth combo are your friends as well.

Nausea is good for you, as it gives you a way to kill off a bunch of little creatures and rebuy their ETB triggers. As Non-Linear points out, Grave Pact is good in your deck. Nausea makes it into a one-sided board wipe.

God-Eternal Bontu seems kind of absurd, with all them creatures you can feed him. With all the sac-ing you're likely to be doing, you might have luck with Harvester of Souls .

I see Demonic Tutor is in your 'Maybeboard.' I feel that this should be in the main deck of any black EDH deck if at all possible. It simply gets whatever you need more efficiently than anything else can.

Qarsi Sadist allows you to drain an opponent for two at each end step, if you have it exploit itself each time and Shirei stays on the board.

Night of Souls' Betrayal is an interesting thought. With a carful build, it could probably bust the deck wide open, as it auto kills each 1/1 and then brings them right back each end step. Pairing it with something like Burglar Rat , Skyscanner , Pilgrim's Eye , Black Cat or other such creatures seems simply rude as ****.

Finally, regarding the lands, I haven't had much luck with Crypt of Agadeem . You might want to replace that, Mortuary Mire and Memorial to Folly with basic lands. I also don't think Ghost Quarter is very good in EDH, unless your meta plays some powerful utility lands like The Tabernacle at Pendrell Vale or Glacial Chasm . Ancient Tomb is a better Temple of the False God , but it is a more expensive card.

Right off the bat, I think you should run Preordain . The card is very powerful, and I see it in your 'Maybeboard.' Second, I saw you replaced Anticipate with Sensei's Divining Top . This is a good idea, but if you're looking for more cantrip effects, Impulse is a strictly better Anticipate . Furthermore, looking at your deck's curve, you might want to consider running Counterbalance in conjunction with top -- I have had good results with that combo, particularly if running Zendikar and Onslaught fetches to clear the top. Azami's draw ability would do just as well though.

I don't think Halimar Depths is a very good card. Sage of Epityr is a one-drop wizard who does the same thing (slightly better, actually) and doubles as card-advantage later in the game. Siren Stormtamer is another good utility one-drop wizard, as is Sidisi's Faithful . (Note that Sidisi's Faithful can be tapped to draw a card while the exploit trigger is on the stack, and you can still have it exploit itself.) Generally any low-cost wizard that has a relevant ability is a good idea. Furthermore, cards like Intruder Alarm and Paradox Engine are your friend, as they make spells into spells plus draw 4 or 5.

Pairing Azami with Mind Over Matter then becomes an auto-win in conjunction with Jace, Wielder of Mysteries . For the record, Laboratory Maniac is a wizard, but I like your choice of Jace better. I think the Lab Man/Jace combos are likely a better way to win than wizard aggro.

Riptide Laboratory is a good way to protect your general.

Sapphire Medallion , which I see is also in the 'Maybeboard,' is also a good card. Mono-blue has little ramp, so any two-drop ramp is good. Same goes for Sky Diamond , Baral, Chief of Compliance and Coldsteel Heart . With more rocks, things like Aphetto Alchemist also get better (I strongly recommend playing him).

I do not recommend Portent . Half the time I use cantrips, I am using them to find a land or some other card I want to use immediately. The Ice Age slowtrips just don't fulfill that need.

Finally, I am not sure I think Arcane Lighthouse or Detection Tower are very good. It may be a meta-call, but I feel that Azami costing triple-blue means you want to run as few colorless lands as possible.

All the best and good luck! Azami was one of my pet decks when I used to play her.

ClockworkSwordfish, The utility of Scrying Sheets seems tempting, but there is rarely any Mana left over for an effect that might add a land into my hand. Coldsteel Heart isn't worth it as it comes in tapped (not a big deal turn 2 or 3 but quite detrimental on turn 8). Also, the point of the Snow-Covered Plains is to help prevent others from benefiting from Extraplanar Lens .

Thanks you for your suggestions, though!!

If you're running snow-covered plains anyway, you might do well to swap one of your mana rocks for Coldsteel Heart and one of your lands for Scrying Sheets . Can't say no to any sort of card advantage in a mono-white deck!

jpermar on Rakdos, Lord's Downward Spiral

A massive update this time. One that I'm very excited about. Here are the changes:

Overall, the deck is faster and more consistent. Here's a summary of changes by card category:

  • direct damage is now at lower cmc
  • -1 Ramp
  • +1 protection/haste
  • +2 tutor
  • +5 draw
  • +1 anti-control
  • -4 Creature removal
  • -2 graveyard hate
  • -1 discard
  • -1 extra attack
  • -1 lifegain/recursion
  • +1 removal

So the changes overall are lower cmc, more draw and tutor, less creature removal and less utility (graveyard hate, extra attacks, etc.) Overall, the early turn plays to get direct damage and get Rakdos out are far more prevalent. The deck is more aggressive and more focused now, and plays much smoother.

And yes, this is the only deck I have where I've taken out Sol Ring . It's simply better to have only colored mana in order to cast Rakdos as consistently as possible!

Alright so this is where things get difficult lol. Right now the deck has some semblance of agro and control but its currently being bogged down by things that don’t contribute anything or enough to warrant their spot. I’m going to suggest a lot of cuts and for each one I’ll offer a decent replacement that will not only make all of our lives miserable but also contribute to making the deck far more resilient and difficult to stop. Creatures to cut

Creatures to Add

Noncreature Spells to Cut

Noncreature Spells to Add

Now what these additions will do is smooth out your mana curve and make you come out swinging far more quickly in more consistently. The additions include another outlet to go infinite through Sword of Feast and Famine and Aggravated Assault . They also contain multiple ways to tutor up Helm of the Host and win. Combat Celebrant and Godo, Bandit Warlord each go infinite with helm and Godo will tutor for it himself and place it straight onto the battlefield.

We also tighten up your control package with cheap removal and creatures that limit what you’re opponents can do. I can provide more explanations in person if you like.

Remember these are only suggestions lol But if you try them I think you’ll like how much faster the deck pops off.

You seem to have a lot of high drops for an aggro deck. Some cards that I would cut would be Debtors' Knell ; it is just too slow for an aggro deck (especially since you have alesha), along with a lot of the other recursion cards. They work well in slower matches, but aggro is not the place for them. In addition, you will want to play as few tap lands as possible. Cut the bounce lands especially for fast lands like Concealed Courtyard . A lot of the minotaurs do nothing other than be minotaurs. I would cut those.

As for replacements, lower drop ramp spells to get your threats out faster (signets, Coldsteel Heart , Sol Ring , Mana Crypt if you have the money), cheap, fast card draw like Night's Whisper and Sign in Blood (NO Phyrexian Arena ), speedier removal (think Disenchant , not Return to Dust ). Depending on meta speed, you may want a Gorilla Shaman for 0 drop artifacts.

Hope this helps a bit.
