Simic Keyrune Discussion

No idea how well it would fun with your deck but Simic Keyrune, our super secret "mana crab"

speaking as a long time polymorph player, you will want some hex proof targets, such as Cloudform or even Simic Keyrune to polymorph. it sucks when you have to waste a polymorph because the other player is holding up red for a bolt when you cast it.

kipahlord13 on How Do You Evaluate Mana-Generating ...

10 months ago

Something that I've heard about mana-artifacts is that WotC would print an a land the same level of abilities that they would on an artifact costing 2. Think the Signet cycle vs Darkwater Catacombs. By that logic, something like the Diamond cycle seems bad, no one wants their basic Plains to etb tapped. By this logic, I consider things that cost 3 to have to be strictly better than 2 counterparts, and much better than something they'd print on a land. Thus Darksteel Ingot is pretty good, as lands can't tap for any color with no strings. However, something like Simic Keyrune seems worse, because it looks remarkably similar to a manland

Tuft on Rashmi's House of Value

Breeding Pool, Flooded Grove, Temple of Mystery, Botanical Sanctum, Hinterland Harbor, and Yavimaya Coast are all relatively cheap (except for the Grove), and will do way more for the consistency of the deck than adding a singleton of Jace - unless, that is, you're going to go for a strong "basics matter" subtheme, which it doesn't look like you're doing.

As far as the deck proper goes, Krasis Incubation, Terrifying Presence, Pulse of Murasa, Reclaim, Natural Connection, Learn from the Past, Nissa's Judgment, Map the Wastes, Contingency Plan, Deep Reconnaissance, Incremental Growth, Vexing Scuttler, Sylvok Replica, Stingerfling Spider, Sigiled Starfish, Shambleshark, Lashweed Lurker, Embodiment of Spring, Dawntreader Elk, Conclave Naturalists, and Borderland Ranger can all be cut. I don't wnat to be frank, but I feel like I have to - those cards are bad. They're simply too low power. From a pure powerlevel perspective, you're going to find yourself outgunned. And although it's really tempting to look for cards like Torrential Gearhulk, Scroll Rack, and Sensei's Divining Top that are "staples" in EDH and are super popular and expensive, those are only really worth it if you've already got a high-power deck filled with high powerlevel cards because it adds consistency to your draws and lets you use your high powerlevel cards to their fullest. I also think that although Scroll Rack and Top are super synergistic with your commander, you should probably save them for last because they're so expensive and relatively low-impact compared to your actual win conditions. If you're on a budget, consider Crystal Ball - although it's a little bit more expensive manawise than either Scroll Rack or Top, it's still pretty damn good.

Your deck is not high powerlevel, sorry to say - although selecting one of your top 3 cards seems really good, it's absolutely godawful useless if the top three cards are Conclave Naturalists, Sigiled Starfish, and Krasis Incubation. Instead of looking to the big ticket cards for power, which will be inconsistent, you should be looking at cheaper synergistic cards - Things that will only cost you a buck or two like Dig Through Time, Vedalken Orrery, Mystical Tutor,Courser of Kruphix, etcetera.

Now with those cuts, that leaves you with 21 extra slots to put in cards that help you with your goal. We need to take a look at your mission statement for the deck and build an idea around which the deck will be built - you said that "The goal is to utilize Rashmi to get insane value from casting cards for free and stealing and copying my opponents cards. Currently has a counters subtheme with most of the creatures". So what can we do with that? Well, looking at clone and stealy effects, you're missing a few really good ones - Stunt Double, Clever Impersonator, Sakashima the Imposter, Cryptoplasm, Progenitor Mimic, and a personal favorite of mine, Phyrexian Metamorph. As far as stealy effects go, there's no shortage in blue. Thada Adel, Acquisitor, Bribery, Treachery, Corrupted Conscience, and Treachery (although this might be a bit out of your price range).

Spelljack is a little costly for a mere counterspell, but it's right in your niche of stealing spells. Cultural Exchange lets you trade away some garbage mana runts for their biggest beatsticks, and Perplexing Chimera is just a lot of fun.

Now all these cards combined will probably not even come close to equaling the cost of a single JTMS, but it'll be much better for your deck if you pick these guys up because your $100 of power isn't focused on one card that you rely on to really blow up your opponent. Instead, it's more evenly dispersed and distributed to make sure that more of your draws are live gas, and less of them are shit like Reclaim.

Also, if you still want better ramp, cut the Simic Keyrune for a Simic Signet, and use Cultivate and Kodama's Reach for your oneshot spells. Although they only drop one land each, they set you up for consistent land drops further down the line, and guarantee you access to both colors.

If you're still interested in a +1/+1 counters subtheme, I've got a lot of ideas, but since you said you're probably gonna phase that out, I'll leave those for another time.

teodorofelipe on Extreme Budget Ezuri, Claw of Progress $21

Prime Speaker Zegana, Edric, Spymaster of Trest and Bane of Progress are almost budget, and pretty powerfull to consider, you could use Simic Keyrune for after a wrath effect. In the future you could go for Animation Module. Some slow lands for helping in mana fixing to consider are Vivid Grove, Vivid Creek, Terramorphic Expanse, Evolving Wilds, Simic Growth Chamber, Thornwood Falls, Simic Guildgate

Pretty cool.

I would get Temple of Mystery and Yavimaya Coast for more lands.

Most of your creatures are pretty cheap mana wise, but maybe Simic Cluestone or Simic Keyrune would be good to add.

I would also recommend Clone, Fated Infatuation, Artisan of Forms, Cackling Counterpart and maybe Stolen Identity. Some or all of these would allow you create more grafters or more snakes, and it's fun to steal your opponents creatures!

One other that comes to mind is Master Biomancer. I'm sure you get the idea!


Alexasmaoao on polymorph thing (send help)

Not of This World is only to protect emrakul while Dispel protects Polymorph or stops opponents instants (if they Path to Exile or Lightning Bolt your Polymorph-target it protects that too). So yes, I would mainboard Dispel and sideboard not of this World. Dispel is Always useful no matter what, while not of this World is very situational, altho strong.

I agree about the keyrune, it's a turn slower. Also I recommended the wrong one. This one is potentially good as a sideboard card if you struggle with opponents removing your creatures when you activate them: Simic Keyrune.

If you want really cheap ways of fixing your manabase slowlands like Rootwater Depths might be okay, since you really only need a few turns.

jellowsmurf on Temur Ramp EDH

Idk, this seems too bold. I think you're in desperate need of some mana dorks or ramp. Rethink some of the creatures and replace them with dorks, or mana rocks.

I would really strongly consider cutting Guardian of Tazeem, Bear's Companion, Akoum Hellkite, Honored Hierarch, Hellkite Charger. Sage of Ancient Lore  Flip, Scourge of Fleets. I also would consider dropping double mana symbols in red or blue if you're not going to run much ramp.

Grab some cluestones/keyrunes/signets in your color schemes Gruul Cluestone, Izzet Cluestone, Simic Cluestone / Gruul Keyrune. Izzet Keyrune, Simic Keyrune / Gruul Signet, Izzet Signet, Simic Signet. Maybe even Temur Banner to help fix mana. Hedron Archive, def a Sol Ring if you wanna ramp, altho I know it's a little expensive.

Nissa's Pilgrimage, Cultivate, Kodama's Reach, Peregrination could help ramp you too. Hedron Archive, the banner and the cluestones get you card draw in the late game.

All that being said, if your deck plays consistently well with your playgroup then disregard everything, but it looks like all beaters and zero room for missing your land drop.
