Coldsteel Heart Discussion

Metroid_Hybrid on Ladies & Gentlemen, Mister Konrad Twitty..

1 week ago

Top is a maybe, but Rings only copies activated abilites, not triggered abilites..

Imp's Mischief doesn't fit that well since I'm usually tapping-out every turn, but I do have a foil copy in my Yawgmoth deck..

You should look at my manabase again.. You missed the other 18 Snow-Covered Swamps, plus the Coldsteel Heart..

Feed the Swarm is brand new, and it will find their way into all of my Mono-Black decks. However I this is more-or-less a Burn deck, not a Control deck.

Myriad Landscape is ramp and doesn't take up a slot, so that is worth considering. Everflowing Chalice is great for these kinds of ramp decks too. With all your glorious sea monsters the big-boy ramp cards will be useful. Gilded Lotus, Mana Vault, Dreamstone Hedron, Thran Dynamo, Nyx Lotus, and Empowered Autogenerator would all be good. Gauntlet of Power, Caged Sun, and Extraplanar Lens are good for decks like this.

Don't underestimate the small rocks either. Sky Diamond, Sapphire Medallion, Prismatic Lens, Star Compass, Guardian Idol, Arcane Signet, and Coldsteel Heart are all good. Burnished Hart is good for heavy ramp in Blue. Personally, I always aim for eight pieces of ramp in most normal decks (which is where you are, including High Tide) but in high-CMC ramp decks I aim for 10-12. Your commander could be considered a piece of ramp since Sol Rings are so easy to steal. Thieving Skydiver could be considered a ramp piece too!

Quicksilver Amulet miiight be worth considering. Far from mandatory. I often prefer pure ramp if the deck isn't super creature-oriented.

Optimator on Yahenni Aristocrats

Your list is looking really good! You have pretty much most of the classic Aristocrats pieces in. Your creature list is spot-on IMO. I love how much removal you have.

A couple of suggestions here though. I am going to assume you're on at least something of a budget. If you're not, hit up EDHREC for more powerful suggestions, of course.

I would recommend a bit more ramp. You're sitting at four ramp pieces by my count, and Bontu's Monument and Ashnod's Altar are a bit questionable as true ramp. They're definitely good and worth their slots--don't get me wrong. I'd recommend at least eight ramp pieces in almost any deck. Some good includes would be Wayfarer's Bauble, Charcoal Diamond, Star Compass, Myriad Landscape, Prismatic Lens, Mind Stone, Worn Powerstone. With a bit of money you have Arcane Signet, Coldsteel Heart, Jet Medallion, Crypt Ghast, Magus of the Coffers and Sword of the Animist.

I wouldn't really recommend Altar of Dementia unless you can infinitely loop sacrifices and make it a win-con. If you just want free sac outlets; your commander, Ashnod's, Woe Strider, and Carrion Feeder should do the trick and give you value in return that you can actually use. Same with Ayara and stuff. Culling Dais and Spawning Pit are decent. One of Yehenni's biggest strengths is having a free sac outlet in the command zone.

Speaking of your commander, one of the reasons to run Yahenni over other mono-Black aristocrats commanders is the threat he/she turns into. I would recommend a few pieces of equipment to help end the game. Loxodon Warhammer, Blackblade Reforged, Lashwrithe, Trailblazer's Boots, Prowler's Helm, and of course Swiftfoot Boots are all good choices. Lots to choose from here but these are great for their price. Obviously there are all the Swords and Jitte and stuff if you have the cash or have them in your collection.

SideBae on The Ur-Dragon CMDR (help needed)

So I mean, the easiest way to improve the deck I can see is to add more 2-mana mana-rocks and potentially some 1-mana mana-dorks. I try to never run more than 32 or 33 lands in non-landfall decks, so cutting 5-6 lands is acceptable if you replace them with mana sources. Note that 3-mana mana-rocks are significantly worse than 2-mana rocks, and should be replaced. Consider running some of the following: the talismans (Talisman of Indulgence, Talisman of Hierarchy and friends), Fellwar Stone, Coldsteel Heart, the signets (Dimir Signet, Orzhov Signet and friends), Birds of Paradise, Avacyn's Pilgrim, Noble Hierarch, Elves of Deep Shadow, Deathrite Shaman, Orcish Lumberjack... All of these are low-cost ways to get more mana. Dropping a rock on turn two and casting a four-mana spell turn three is much better than ramping on turn 3, in my experience. With the exception of Noble Hierarch, I think all these cards should be well under $20.

SideBae on Atemsis, Misplay-Seeing

1 month ago

I actually think this deck looks amazing -- I'd love to play against it! I do have a few suggestions though. Mind you, they vary widely in price, so some may or may not be more applicable than others.

  1. The most straightforward way I can see to improve here is by improving your manabase. Fetches are largely unimportant in mono-colored strategies, but if you can afford them I'd definitely run them. They shuffle after Brainstorm for free, but perhaps more importantly they fetch Mystic Sanctuary, which lets you stack what you need from your graveyard on top of your deck. If the Zendikar/Onslaught fetches are out of your price range, consider slow fetches (Flood Plain, Bad River)...

  2. A card that comes to mind is Ideas Unbound. I feel like having a critical mass of cards in your hand is key to slaying someone with Atemsis, and Ideas Unbound lets you you get cards in your hand and gives you time to reveal them to an Atemsis trigger. Honestly, IDK how good it'd be -- but it's probably worth a try.

  3. Depending on how often you activate Atemsis's looting ability, you could consider running some madness cards. Circular Logic and Just the Wind come to mind, but Welcome to the Fold might be good, too.

  4. You've got some good ramp, but I think there're a few 2-drop rocks you may have overlooked. Coldsteel Heart is pretty good as an admittedly worse Arcane Signet, and Everflowing Chalice is pretty good, too. If you're willing to invest, Chrome Mox and Mox Diamond are also in most of my decks.

  5. Fierce Guardianship is a good piece of protection for your combo. I run it in most of my blue decks, and it's pretty good.

  6. One particularly salt-inducing card is Commandeer. Since it was templated before planeswalkers happened, it can steal them -- for no mana, btw. Also, as a 7-drop, it takes a more uncommon slot for mana-cost for your commander triggers.

Right. I think that's all I got. Good luck

Coldsteel Heart is a strictly better mana rock than the diamonds, I'd probably swap out Fire Diamond for it.

AjanisLastDan on Mill hard play hard

Mastermind's Acquisition could replace Razaketh's Rite, (since Demonic Tutor will never go down in price) unless your opinion is that the cycling ability is worth the extra mana.

Talisman of Dominance, Coldsteel Heart, and Prismatic Lens are useful, relatively inexpensive artifact ramp.

Tree of Perdition and Undead Alchemist combo off with your commander to mill your opponents and flood your own board with zombies.

Just my two bits.

LittleBlueHero on Blessings of Saint Traft

Hey there,

I just put together a blue white voltron deck as well. I run hannah, ship's navigator at the moment to attempt to mitigate having any of my threats wiped. She also draws me a little less attention at the table.

But I really just wanted to let you know how much I have loved Shinechaser in the deck. It functions as a Bruna Lite with its flying and vigilance and is almost always a 3/3 flying vigilance for 3 mana in my deck. Add any buffs to that and she's a great threat at a low cost.

Also if you are looking for better ramp than the locket and cluestone check out Wayfarer's Bauble, Coldsteel Heart, Fractured Powerstone, Everflowing Chalice, Fellwar Stone basically anything that only costs 2 mana will really help out since your deck wants to be as aggressive as possible. Also turn three you want to drop your commander so the less cards you have competing with his slot the better.
