Coldsteel Heart Discussion

How's it going? I've been tweaking my Krenko deck! Have you seen Coldsteel Heart? It's like another Fire Diamond, which I always love seeing. I'm also going to mess with Myriad Landscape. Ramp is so good in this deck. I need a Mana Crypt.

I've played a lot of this deck and I've tried both Coldsteel Heart and Magma Jet and neither of them work very well (at least int the current meta). Magma Jet can be used in a flex slot, but I have Sweltering Suns there right now. Magma Jet is a dead card more often than not, as I already have 9 other removal spells and I can cycle the Sweltering Suns for more card advantage than the Magma Jet.

As for Ensnaring Bridge, it's just too expensive for how useful it is to me right now.

No Ensnaring Bridge? also Coldsteel Heart and Magma Jet are two cards I like for your underwhelming 2-drop slot (you might be slightly heavy on threats)

Ok had some time to review. The main thing that stands out to me is a lack of ramp. Obviously Mana Vault and Mana Crypt come to mind, but at a more reasonable price we have cards like Fire Diamond, Thought Vessel, Coldsteel Heart, and Fellwar Stone. The point being to play your commander asap which should always be before turn 4 unless counter magic is blocking you. Pyretic Ritual and Desperate Ritual are good too but you would want to run things like Reforge the Soul and at the higher end Wheel of Fortune to replace those cards from your hand.

Combat Celebrant also goes infinite with Kiki-Jiki, Mirror Breaker.

Norin the Wary and Genesis Chamber are great cards to look at. I'll drop my girlfriend's Norin the Wary deck here as it has a lot of good cards to consider for what you are doing here.

I've mentioned it earlier but I think it's worth noting, with your current archetype in mind, that there isn't enough of a support package to fully utilize Mana Vault. I think you're safe on replacing it with Gilded Lotus or any 2 CMC Monoblack rock: Coldsteel Heart, Charcoal Diamond, Jet Medallion.

The untap during upkeep clause, paying 4, deals damage to you if you don't. I don't like all of these factors about this card.

Honestly in retrospect, cut it for Basalt Monolith, which will open up an avenue for infinite mana w/ Rings of Brighthearth into Exsanguinate or Torment of Hailfire.
