scotchtapedsleeves on EDH: Saheeli's Mana Rocks You

1 week ago

Coming from the Advertise your Deck forum.

I like the ideas you've thrown in with for the upgraded precon, but your mana base could use some work. I'd cut lands down to 35-36 and replace a few of your slower rocks (eg. Magnifying Glass, Unstable Obelisk) with an Izzet Signet, Darksteel Ingot or Honor-Worn Shaku. Remember, you're not just playing colourless spells!

Additionally, your mana curve is a bit out of wack. Throwing expensive cards in your deck looks fun, but it won't play well unless you have consistent ramp. Spine of Ish Sah doesn't seem to be doing much unless you have a combo in mind. I don't love Planar Bridge. Myr Battlesphere doesn't have much use unless you add more Myrs (speaking of, Palladium Myr, Silver Myr, Alloy Myr).

You don't have much card draw, I'd add Brainstorm, Fabricate, and Ponder.

I'm also not a huge fan of the 4 planeswalkers, those slots could probably be better used with more artifact generation or counterspells.

Hope this helped!

Metroid_Hybrid on Wastes, over-easy

legendofa: Good catches..

I have been meaning to replace Seer's Lantern with the new Pauper-legal(izing) printing of Unstable Obelisk.

However, I was unaware of, or forgot about the Goblin Firebomb. What do you think I should trade-out for it?

Goblin Firebomb and Unstable Obelisk are a couple more options for general-purpose removal.

I have replaced Unstable Obelisk with Pernicious Deed, because, as awesome as the obelisk was, the deed is too good to not put into this deck; it is unfortunate that I now have one less source of mana in this deck, but it still has plenty of mana sources, in my mind.

Personally I would make these swaps:

in:
+ Goblin Engineer
+ Unstable Obelisk
+ Bloody Betrayal
+ Commander's Sphere
+ Spark Double
+ Crowded Crypt
+ Letter of Acceptance
+ Izzet Locket
+ Rakdos Locket
+ Dimir Locket
+ Whisper, Blood Liturgist

out:
- Dreadmalkin
- Hobblefiend
- Ravenous Harpy
- Laurine, the Diversion
- Yahenni, Undying Partisan
- Angrath, the Flame-Chained
- Jace, Ingenious Mind-Mage
- Undercity Informer
- Thoughtpicker Witch
- Claws of Gix
- Tibalt, the Fiend-Blooded

I have replaced Gilded Lotus and Thran Dynamo with Decanter of Endless Water and Unstable Obelisk, but, for some reason, the average converted mana cost of this deck remained the same, at 3.18, which it most certainly should not have done, but I am confident that have I still lowered this deck's mana curve, nevertheless.

I do appreciate everyone suggesting that I use land-based mana acceleration in this deck, and I do, in fact, have Sakura-Tribe Elder in it, as it fits the theme of the deck, but I specifically mentioned those two artifacts, because they have secondary abilities beyond producing mana, and, between those two, I have decided to use Unstable Obelisk, since this deck already has a sufficient number of cards that allow me to draw more cards.
