Hello awesome Commander fans! Wow, do I have something fun for you today! Debuting in the Commander decks made for the Commander Masters reprint set was 40 new cards with 10 new cards in each of four decks with each of two new Commander legal legendary Commanders. So that's eight new options for Commander format, and then these were made for the format, so they should hit higher than normal legendary critters in sets like my recently done Wilds of Eldraine Commander tier ranking which you can find here - (Ranking Wilds of Eldraine's Legends As Commanders | Article by Abe Sargent (coolstuffinc.com)). Unlike that article, this one will be ranking them not just by category but in order from best to worst.
S Tier
Let's start with my top two cards in the format, Zhulodok, Void Gorger and Sliver Gravemother. These are awesome options for your next Commander brew. As you can see, the Zhulodok costs colorless mana, so you'll need to add that to your deck. It has a mana value of six, and offers a fun 7/4 body. Then when you cast a 7-drop or higher, you cascade twice, so you'll have to have expensive spells to trigger the cascade and then cheaper stuff to cascade into, leading to some interesting deck-building tension. Colorless cascade is a fun restriction, challenging you to think a little differently than your usual cascade builds (like Maelstrom Wanderer). It feels fair.
Next up is the five-color Sliver Gravemother, the latest option to lead your Sliver deck since the iconic diva Sliver Queen started it all! The legend rule doesn't apply to Slivers while the Gravemother is in play, and then all your Slivers get encore equal to their mana value. The Gravemother also has encore, so when it's dead you can bring it back once.
Let's finish S Tier with this legendary planeswalker that can be played as a Commander! Commodore Guff costs four, has a strong five starting loyalty and then has three abilities. Your End-Of-Turn trigger will put a loyalty counter on another 'walker, so that's good in brews with multiple planeswalkers. His +1 will make a 1/1 Red Wizard to block attacks or tap to make mana to cast more planeswalkers, which seems pretty good. His -3 draws X cards and deals X damage to each opponent, where X is equal to your planeswalker count, so that's card draw and player kill in one ability you can lean in on hard. Planeswalkers are a popular archetype, and he plays well in that space!
A Tier
Now let's turn to my two A-Tier options, Leori, Sparktouched Hunter and Anikthea, Hand of Erebos, both in White! Leori costs three, which is cheap for a three-color option, with both flying to evade and vigilance to get in swings with flying and stay back to block. This Cat has a combat damage trigger with that flying. You name a planeswalker type like Jace or Ajani and the their abilities can be copied when activated this turn. I love how differently this plays than Commodore Guff even in the same deck and archetype.
Anikthea costs five for a 4/4 with menace - also evasive. Note she is an enchantment creature, and she grants your other enchantment creatures menace as well. Then when she Enters-The-Battlefiend or attacks, you exile up to (you don't have to) one non-Aura enchantment from your graveyard to make a creature copy of that that's a 3/3 black Zombie in addition to its other types. Don't forget that's an ETB and attack trigger, like Sun Titan.
B Tier
Now, let's finish with my triad of B-Tier options. Narci, Fable Singer is awesome as a 4-drop 3/3 with lifelink. Then when you sacrifice an enchantment of any sort, like enchantment creatures or things like Seal of Cleansing, draw a card! No mana or tapping needed and it's not limited to just once per turn. Then when the final chapter of a Saga resolves, you gain life and your foes lose life equal to that saga's mana value. Mark built around it here - How to Sacrifice Enchantments for Value With Narci, Fable Singer | Article by Mark Wischkaemper (coolstuffinc.com). It's awesome, but Saga support is done better with other Commanders like Tom Bombadil. The five-color 5-drop Rukarumel, Biologist is a smaller 3/3 size too. When she Enters-The-Battlefield you choose a creature type, and then your Slivers and other non-token dorks are now that type too. That also includes the stuff not on the battlefield. So, for example, you could name Zombie and then add in stuff like Lord of the Undead to pump all of your stuff by +1/+1 and then recur it to your hand from your graveyard by tapping it. That's a strong Johnny/Jenny method of playing with fun creature type matters stuff! But she's hard to cast, forces you into five colors, and has a small body.
Let's finish with my least favorite Commander from the set, Omarthis, Ghostfire Initiate, a colorless double that arrives with X counters on it. When one or more +1/+1 counters are placed on a colorless creature, you can also toss one here, so it's colorless +1/+1 counters matter. When it dies, manifest equal to your counter count. It's pricey already with an cost and then a Commander Tax after the first death seems hard in colorless without Cabal Coffers, Green's ramp, mass Treasure makers in Red, or Nykthos, Shrine to Nyx, and that's rough. +1/+1 counters are beloved as the 4th most played Commander archetype (All Themes | EDHREC), but making It just colorless seems a hard task to pull off. However, Matthew built around it here (Collecting Colorless Counters in Commander | Article by Matthew Lotti (coolstuffinc.com)).
I hope that you enjoyed this fun take on the new Commander options from Commander Masters Commander!
