Maybeboard


Hello! If this decklist looks familiar, that's because it's mostly composed of the C21 precon deck.

I'm participating in a challenge with 4 other players. On April 26th (just a few days after release), we played multiple games with the five Commander 2021 preconstructed decks. Every week following the first, we're replacing a fixed number of cards from the precon list and returning to duel the decks against each other. It's essentially a slow-grow league where we see who can make the most impactful changes the fastest.

I thought it would be fun to keep track of the deck's evolution over time. The Mainboard is the current decklist; the Maybeboard will accumulate the list of cards that have been cut from previous iterations (mostly precon chaff.) Weekly changelogs appear below.

In:

Helm of the Host

Spark Double

Double Major

Quasiduplicate

Spell Swindle

Swan Song

Arcane Denial

Whirlwind Denial

Reclamation Sage

Reliquary Tower

Out:

Desolation Twin

Spawning Kraken

Fractal Harness

Ruxa, Patient Professor

Kaseto, Orochi Archmage

Biomass Mutation

Forgotten Ancient

Tranquil Thicket

Novijen, Heart of Progress

Opal Palace

Thoughts:

Cuts were not hard to find for the first week. The base precon contained many dead cards like Forgotten Ancient and Plaxcaster Frogling focused on +1/+1 counters, as well as mediocre cards like Ruxa, Patient Professor and Biomass Mutation that interact with Fractal tokens but don't do much else. Additionally, the deck had too many lands (especially given its many card-draw spells) and too many high-cost cards (roughly 10 cards with either 6+ mana value or X in their cost.) I did the best I could to clear the least useful ones, but the deck's mana curve is still too steep for my liking.

Adding cards was more difficult. I want to make Adrix & Nev into a Clones-matter deck, where I can make a few token copies of my commander and then get a huge multiplier to make dozens of treasure tokens or token copies of Command Tower via Replication Technique . Unfortunately, the base deck was also lacking in basic interaction, with zero counterspells and mediocre removal outside of Beast Within and Perplexing Test . I threw in a few cards to start allowing me to clone Adrix & Nev, but the top priority had to be interaction spells, particularly Whirlwind Denial to deal with the stormy nature of the other precons.

In:

Birds of Paradise

Elvish Mystic

Llanowar Elves

Quandrix Command

Eternal Witness

Risen Reef

Sailor of Means

Corsair Captain

Second Harvest

Saheeli's Artistry

Out:

Geometric Nexus

Golden Ratio

Sequence Engine

Plaxcaster Frogling

Guardian Augmenter

Deekah, Fractal Theorist

Rampaging Baloths

Esix, Fractal Bloom

Hydra Broodmaster

Hornet Queen

Thoughts:

More than anything else, my focus for cuts was to start shredding away at the deck's ridiculous mana curve, rather than working on the mediocre-but-playable mana base. Even after a week of changes, the deck still had a pile of eighteen cards with mana value of 5 or higher, most of which I had never cast. While it's true that Adrix & Nev need cards that make tokens before they can become powerful, I still cut many overcosted cards like Hornet Queen that were only in the deck for the sake of having a card that makes a token. I shall miss only Hydra Broodmaster .

As for inclusions, I gave the deck its much-deserved Quandrix Command (they printed a cycle of those, and then didn't include them in the precons. Why?) as well as 3 functional reprints of Llanowar Elves. This week the deck managed to create copies of Adrix & Nev with moderate consistency, so I'm adding in a couple more token-generating cards in the form of Saheeli's Artistry and Second Harvest . I particularly want to abuse whatever small Treasure-token subtheme I can, so a couple of generic pirates went in, and Eternal Witness is going to have to hold down a particularly slim niche for recursion, which the deck needs BADLY. Finally, I decided to test Risen Reef as a copy target over cards like Wood Elves and Solemn Simulacrum , though those will probably all make it into the final build.

Due to players being ill/busy, we chose to skip a week

In:

Collective Voyage

Counterspell

Mystic Remora

Reality Shift

Archaeomancer

Out:

Study Hall

Llanowar Reborn

Lonely Sandbar

Terastodon

Master Biomancer

Thoughts:

We had to play with 4 out of 5 players this week so we cut the amount of changes in half out of respect for the player who missed the session.

I would like to slowly push towards more aggressive win conditions, eventually looking towards adding cards like Avenger of Zendikar , Sharding Sphinx and Thassa's Oracle . However, I am currently still focused on improving the deck's ramp and control packages and tuning its curve. In particular, Terastodon and Master Biomancer stood out as cards that do impressive things on a winning board state, but are otherwise overcosted targets for clone effects. While I'm sad to see Nasty Terasty go, it's the right decision for the deck's mana curve.

The other main problem the deck was facing was mana flood. Given the huge amounts of ramp I have been slotting into the deck, the land count was far too high, so I cut 3 of the weaker nonbasic lands. I would like to eventually improve the deck with Hinterland Harbor , Breeding Pool and Waterlogged Grove , among others. I am still worried about the density of cards simply designed to flop tokens into play and do nothing else, such as Kazandu Tuskcaller , Reef Worm , Hornet Nest , and Paradox Zone , but for now I do not have enough cuts to fix these problems.

For inclusions, I particularly wanted to add Archaeomancer , as Eternal Witness has been overperforming over the last couple of weeks. With Adrix & Nev out, cloning an EWit not only brings back the clone spell but also draws another card out of the graveyard, and this is an interaction I very much want to abuse, given this deck's tendency to durdle around making huge mana pools. Counterspell and Reality Shift are into the deck for more control, which I badly need against Prismari Storm. Collective Voyage outscales almost every other ramp effect in the deck, while Mystic Remora does the same for draw; hopefully I can start paring down excess value cards by card quality in the weeks to come.

Out:

Hornet Nest

Kazandu Tuskcaller

Trygon Predator

Arashi, the Sky Asunder

Primal Empathy

Nissa's Expedition

Eureka Moment

Curse of the Swine

Managorger Hydra

Forest

In:

Mimic Vat

Negate

Glen Elendra Archmage

Stolen Identity

Thassa's Oracle

Amphin Mutineer

Mulldrifter

Avenger of Zendikar

Solemn Simulacrum

Hinterland Harbor

Thoughts:

This marks the first week where my alterations have upped the mana curve overall. Additionally, this is the first week where a few of my swaps were simply direct improvements to individual cards. Examples: Curse of the Swine became Amphin Mutineer , Nissa's Expedition became Solemn Simulacrum , Eureka Moment became Mulldrifter .

As the overall focus of the deck has shifted onto a clones strat, I've been forced to play along with built-in antisynergies within the original deck. I'm finally getting to the point where I'm happy enough with the way the deck is built holistically that I can start cutting objectively decent cards like Managorger Hydra and Kazandu Tuskcaller in favor of more fitting replacements like Avenger of Zendikar and Mimic Vat .

The deck is still running a couple of antisynergistic "big stuff" matters effects, notably Garruk, Primal Hunter and Return of the Wildspeaker , and therefore I'm still leaving a few generators of thick tokens like Reef Worm and Paradox Zone in the deck for now.

With the addition of Stolen Identity , the only major token-clone effects I'm omitting are Cackling Counterpart and Progenitor Mimic . The former I cannot find a copy of, and the latter I find to be too slow for this deck's playstyle.

The deck is getting bluer and bluer over time, so I'm slowly overwriting Forests with fixing/duals like Hinterland Harbor .

Of course, the elephant in the room is Thassa's Oracle . I will never tutor Oracle, I will never cheese Oracle with cards like Leveler , I will simply attempt to clone enough creatures that I either a) draw my deck or b) have more than 100 devotion to blue. Very few of our games have been won with mere combat damage; Ignite Memories and Aetherflux Reservoir have more kills than creatures do in our pod. So I feel justified adding an alt-wincon at this point.

And that ended up being it! The fully upgraded version of the deck is at:
