ASalesman on Unesh, Ultimate Guide (Tribal)

4 weeks ago

A controversial substitution perhaps, but deserved

Replacing Omniscience with Moonsilver Key.

Why not Omniscence?

• Omniscence is too mana intensive in this deck. In your opening hand it is completely a dead card 90% of the time. In the 10% you have a line to play it in your opening hand, you are putting all your eggs into 1 basket. Omniscence is too high risk for the reward. If this spell doesn't resolve (and it likely won't at a cEDH table) you lose the game.
• Even the times it does resolve in the early game, your hand doesn't always have enough steam to win outright.
• It is important for all cEDH decks to consider how a card will function in your opening hand as well as later in the game. I'll write more about this topic in the current theory module of the guide. This inconsistency in the opening hand is what makes it bad. It is true that other cards in the deck are similar, but they aren't as mana intensive as omniscience. Omniscence in my opening hand has lost too many games.
• Omniscence is essentially a combo by itself while Unesh is on the field. It is clunky at best because it doesn't always guarantee you get to the bottom of your deck unlike Rite of Replication. Recent powerful revisions of the deck have led to anti-synergy with this card. Example 1, removal of Long-Term Plans. Example 2, the addition of Palinchron makes infinite mana and storm more attainable than with Omniscence due to the reduced mana cost.

Why Moonsilver Key?

• I think this card might be as much of a blindside to you as it was to me. I knew Omniscence had to go, so I started researching what I would replace it with. And I found this card. This card is the most opposite of a clunky opening hand card I could find. Rather than having a dead Omniscence in your hand, you can spend your early turns playing this card and getting an important mana rock like Jeweled Lotus & Mana Crypt or an Island.
• The deck has been short on mana rocks. With a mana rock tutor in this slot combined with Virtue of Knowledge and fetch lands I have noticed a significant uptick in ramp reliability in my opening hands. I have been throwing around ideas like Mox Diamond, Mox Opal, and Mox Amber but none of these cards reliably solve Unesh's problems in the opening hand. I also considered Lion's Eye Diamond which seems a little too high risk IMO, because then your fate relies on the subsequent BFOF from casting Unesh. The runner-up contender was Fellwar Stone, essentially a worse Arcane Signet wouldn't be bad. It is important for Unesh to ramp out ASAP, and having a mana artifact tutor in the early game seems to help with that plan, and it thins the deck.
• Minor point, it enjoys synergy with the adventure mode of Virtue of Knowledge.

What are your thoughts on this sub? Could I be doing better here?

Cataclysm can work against you based on opponents' picks and though Enter the Infinite is impressive & works with Omniscience, I don't see Thassa's Oracle or Laboratory Maniac, nor do I see Grapeshot. Consider instead Boros Charm + Armageddon which most people will hate & sometimes outright scoop after.

Mana Vault is more of a risk than you might think without untap mechanics (See Derevi, last paragraph). Consider Thought Vessel or even Library of Leng.

Replace Lion's Eye Diamond with Land Tax. The latter also helps offset the pain from Need for Speed, which is a cool find.

Consider Smothering Tithe instead of Mystic Remora: Remora usually only nets a few cards at beginning, and will often slow you down more than it helps. The former performs MUCH more consistently, and will net you more mana to focus on spells and counters.

Concerning your SB: If you want to go maximum lock-stax, I'd recommend Derevi, Empyrial Tactician. Use Winter Orb, Static Orb & Stasis, use Kismet and Loxodon Gatekeeper, maybe even Elesh Norn, Mother of Machines. Use fetches + basic lands, huge ramp, and Back to Basics just to spite opponents. NB: Mana Vault smacks with Derevi.

DreadKhan on No Holds Barred Magic

If you're going with Show and Tell (I'm pretty sure you want 4 of this, and maybe a Mystical Tutor), why not Omniscience? Once that's out you can just cheat out everything. Also, if you're going for no rules magic you want Ancestral Recall, it's really good. Another option to consider is Eureka.

Hope some of this is helpful!

The_Dragonmaster on Interaction between Archaeomancer and See …

3 months ago

I'm wondering what happens when I cast See Double to create a token of Archaeomancer.

Let's say our opponent has 8 cards in his graveyard. He casts Lightning Bolt, and in response I use see double to both copy Lightning Bolt, and create a token copy of Archaeomancer. Would the token be able to return See Double to my hand? And if so, if I had Omniscience, could I in theory recast See Double for infinite tokens and infinite Lightning Bolt copies before Lightning Bolt resolves?

Licecolony on How to Train Ur-Dragon

Well. Looking at the deck, I'd be trying to find ways to reduce your average mana-cost and make sure your higher mana-cost cards have the impact you're looking for.

For example, comparing a card like Temur Ascendancy and Crucible of Fire. Your average dragon has 5 power. Temur Ascendancy allows your to hit with that dragon one turn earlier, while crucible makes it such that your dragon hits for 3 more damage when it does. In a damage comparison, say you play a 5 power dragon. Turn 1: 5 damage with Temur Ascendancy, 0 damage with Crucible of Fire

Turn 2: 10 damage with Temur Ascendancy, 8 damage with Crucible of Fire

Turn 3: 15 damage with Temur Ascendancy, 16 damage with Crucible of Fire

It takes 3 turns of unblocked damage for your dragon to be more effective with a Crucible, than it would have been with just a haste outlet like Temur Ascendancy. And that doesn't even take into account the Ascendancy card draw. And it's a mana cheaper.

So I'd get rid of cards like City on Fire (you don't want to use your dragons to make mana, you want to use them to attack), Crucible of Fire (your dragons are big, this is a good card if you have a bunch of dragons in play, but if you have a bunch of dragons in play, you also don't really need it to win), Fiery Emancipation (Same argument as city on fire), Omniscience (I know, FREE dragons, but ideally, you have enough mana not to worry. Omniscience is great for decks where you have a lot of card acceleration), Doubling Season (You don't actually have that many cards that make tokens, if you want that kinds of effect, Reflections of Littjara will serve you better).

You might consider Mind_Blower3's dragon cheapener suggestions. Another really good one for your deck would be Dragon's Hoard

Update: As I was playtesting with the deck today, Collected Conjuring just seemed less and less useful because of how slow it was, and Demonic Dread started looking like a MASSIVE hitter. So, I took out 2 copies of the Conjuring for another pair of Omniscience because fuck me why am I not running 4 anyway, and remembered the Shark Typhoon, and realized it could also be amazing in here.

Spirits on Yuriko, Shadow of Fate EDH

Still unsure what to replace Doomsday with, was trying to figure out if there is an Intuition win? Show and Tell + Omniscience + Enter the Infinite seems to work with the high CMC on them, hmm.

Wondering if I should focus more on the damage aspects (above would help with that too) instead of Doomsday.

The 3 CMC tutors seem heavy, and the Grazilaxx, Illithid Scholar gets lots of hate. Thinking maybe more ninjas to try and draw more.

Still needs tweaks, but can't figure out what to do.

raincoat on Knowledge & Power - Alaundo Haymakers

Love this deck. Any reason for not running Intruder Alarm?

Have you found it too enabling for other decks, such that Alaundo never gets to capitalize off of it enough? Had a game the other night with this deck & the friendly neighborhood Shorikai, Genesis Engine player dropped an Intruder Alarm. Alaundo receiving numerous free untaps allowed me to snowball the game & cheat out Omniscience + plenty of draw to pull three counterspells, winning the game on my next turn. Thinking of including Intruder Alarm in this deck just because of that, but I can see situations where it can enable other players to out-combo you.

Either way, very fun deck - great work!
