Prismari Mastery Precon Upgrade Guide

73 Views
Article Index

Commander Overview

The Prismari are the artistic performers of Strixhaven, using their magic to perform masterful displays of color and music. The Prismari Mastery commander deck, led by Rootha, Mastering the Moment, focuses on casting large spells to create Elemental tokens.

The payoffs for blue-red spellslinger decks are usually storming off and pinging the table for a lot of damage, but this deck focuses on casting increasingly large spells, copying them, or making copies of creatures.

This is a neat take on the color archetype, and the deck features a few interesting cards, such as Muddle, the Ever-Changing and Renegade Bull.

In this upgrade guide, I aim to trim some of the fat off the deck and throw in a few staples that were missing from the list.

What We’re Removing

I identified 15 cards that could be removed from the precon. They are either too expensive for the effect, too slow, or unnecessary (Temple, I’m looking at you). Here’s a full list of what we’re getting rid of:

Cards to Remove:

Mana

In my typical fashion, I’m getting rid of the filter lands Cascade Bluffs and Ferrous Lake as well as Terramorphic Expanse and Temple of the False God. This deck had 38 lands, instead of the 37 the others had. The spells tend to have higher CMC than the other decks, but with a few adjustments, the deck will work just fine with fewer lands.

I also removed Fellwar Stone because we have a lot of mana rocks already, and I’ll be adding in one more.

Creatures

The first iteration of Rootha, Rootha, Mercurial Artist, isn’t a bad card, but I’ve found that the versions from original Strixhaven don’t work as well in these decks as we might have hoped. She’s an expensive copy-spell effect, 5 mana total for a copy is not economical.

Additionally, I’m expelling Curiosity Crafter, simply because it’s conditional card draw. There are better ways to draw cards for 4 mana.

Mirrorwing Dragon was a tough card to cut, but there aren’t many ways in the deck to make use of its ability. If there were more individual pump spells, it would be a nice addition.

Instants and Sorceries

Rapid fire here, I’m removing Chain Reaction, Deep Analysis, Replication Technique, and Aether Gale because there are stronger cards that do the same thing for cheaper. Similarly, I’m removing Abrade and Arcane Denial because they’re not as powerful as theft could be. Abrade is good, don’t get me wrong, but I think this deck should have a smaller interaction package and focus on going faster and being impactful than being board-police.

What We’re Adding

I love spellslinger decks, and I had a hard time picking the right cards to include here. There are some staples that made it in, like Goblin Electromancer, but there are also some cool cards that work great with Rootha’s gameplan.

Cards to Add:

Mana

For faster mana, I added in the Izzet shockland as well as Riverpyre Verge. The verge is quite pricy these days, so if it’s too much for you, I suggest looking at Riverglide Pathway instead.

I also included the new card from Secrets of Strixhaven, Resonating Lute, which makes it possible to cast massive spells and draw more cards. Pyromancer's Goggles also taps for mana with the benefit of behind able to copy red instants/sorceries.

Creatures

Goblin Electromancer is a staple for any spellslinger archetype, and it just adds to the probability of pulling a cost reducer in your opening hand.

Hydroelectric Specimen is a nice instant-speed deflecting effect, used to protect Rootha or other important players. If you’re desperate for mana, you can also play the back side as a source of blue mana.

Magnus the Red provides insane amounts of cost reduction, and also creates tokens himself. I think he’s worth the $10 you’d spend on him.

Instants and Sorceries

The biggest improvements to the deck are in this section. Many of the cards we removed were not cost effective for the results (even though they made big elementals with Rootha). To remedy that, I’ve added in some better variants.

Frantic Search is objectively good in a spellslinger deck, while Counterspell is better than Arcane Denial, if more pip-intensive.

Aetherize provides more protection at instant speed than Aether Gale, even though it only targets creatures.

I have also added in some big hitters in this section to help with Rootha’s elemental farm. Insurrection is a game ender in most instances, and Mnemonic Deluge opens the doors for so many possibilities. If you target Dig Through Time, you can look at the top 21 cards, drawing 6. Alternatively, you could target Creative Technique if you feel like gambling off the top.

I’ve also included Invoke Calamity as a way to get more value from your graveyard. You’de make a 5/5 elemental and be able to recast Frantic Search, Chaos Warp, or Counterspell from the yard at instant speed. It’s just a versatile card.

Enchantments

As another cost reduction/card draw engine, I’ve included Case of the Ransacked Lab. And to add another layer of creature token production, I’ve slotted in Metallurgic Summonings. This card also is awesome graveyard recursion for all your instants/sorceries.

Conclusion

I think this commander deck is a fun take on the blue-red spellslinger archetype. Casting massive spells with multiple payoffs is very flavorful. I think this is probably one of the weaker precons from Secrets of Strixhaven, with Lorehold and Silverquill coming in as the best.

But, this deck is fun and has good bones for future upgrades!
