Phyrexia: All Will Be One has given MTG players plenty of new Commanders and Commander cards. The set contains 28 new legendary creatures, alongside six additional choices released in the pre-constructed decks and in set boosters. The communities delight over the new Myr commander
Urtet, Remnant of Memnarch

At the beginning of combat on your turn, untap each Myr you control.
{W}{U}{B}{R}{G}, {T}: Put three +1/+1 counters on each Myr you control. Activate only during your turn.
is mirrored by the wary caution with which the Rules Committee are regarding
Elesh Norn, Mother of Machines

If a permanent entering causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.
Permanents entering don't cause abilities of permanents your opponents control to trigger.
.
Amidst all of this, one new commander is quietly rising in popularity:
Graaz, Unstoppable Juggernaut

Juggernauts you control can't be blocked by Walls.
Other creatures you control have base power and toughness 5/3 and are Juggernauts in addition to their other creature types.
. According to data on the Commander deckbuilding website EDHREC Graaz is, at the time of writing, the fifth most popular Commander from the main set. With The pre-release just over a week ago, 393 decks are already listed with Graaz as their commander. This is somewhat surprising as Graaz is an eight-mana colorless card, making it a costly card in a niche archetype. Nevertheless, players seem to have taken a shine to this unstoppable juggernaut and are excitedly brewing decks around the gigantic Mirran menace.
An Unstoppable Strategy

Juggernaut

This creature can't be blocked by Walls.
is a card that has been a part of Magic: the Gathering since the beginning. Introduced back in Alpha in 1993,
Juggernaut

This creature can't be blocked by Walls.
is a four-mana 5/3 artifact creature. Juggernaut must attack every turn it is able to and cannot be blocked by walls.
Graaz, Unstoppable Juggernaut

Juggernauts you control can't be blocked by Walls.
Other creatures you control have base power and toughness 5/3 and are Juggernauts in addition to their other creature types.
takes all of your other creatures and turns them all into Juggernauts. Every other creature you control while Graaz is in play becomes a 5/3, that must attack each turn and cannot be blocked by walls. Graaz even provides all of your other creatures with the Juggernaut creature type.
The implied strategy is clear. Fill your deck with colorless creatures which are either mana dorks, like
Palladium Myr


When this creature dies, you may draw a card.
. Cards which generate a large number of small artifact creature tokens are also useful. This is especially true if those tokens have flying, or other relevant keyword abilities, like the ones generated by
Thopter Assembly

At the beginning of your upkeep, if you control no Thopters other than this creature, return this creature to its owner's hand and create five 1/1 colorless Thopter artifact creature tokens with flying.
. Once you have reached eight mana, bring out Graaz and turn your board of unassuming utility creatures and 1/1 tokens into an army of 5/3 battering rams to overwhelm your opponents.
Cards that can help you get Graaz into play are in high demand here, due to the Juggernaut Commander’s high mana value.
Ugin, the Ineffable

+1: Exile the top card of your library face down and look at it. Create a 2/2 colorless Spirit creature token. When that token leaves the battlefield, put the exiled card into your hand.
−3: Destroy target permanent that's one or more colors.
makes all colorless cards, in other words, all of the cards in your deck, two mana cheaper which is hugely helpful.
Forsaken Monument

Whenever you tap a permanent for {C}, add an additional {C}.
Whenever you cast a colorless spell, you gain 2 life.
provides an absolutely immense amount of value. The monument gives all of your colorless creatures +2/+2 and gives you an additional colorless mana every time you tap a Waste or another permanent that generates colorless mana. As a bit of extra icing, the monument also gives you two life whenever you cast a colorless spell.
Other useful cards include:
All Is Dust


Equip commander {3}
Equip {5}
gives the equipped creature protection from every color and
War Room

{3}, {T}, Pay life equal to the number of colors in your commanders' color identity: Draw a card.
allows you to draw cards without paying any life as your Commander has no colors in their identity.
Stonecoil Serpent

This creature enters with X +1/+1 counters on it.
also shines in this deck. Since the card has default stats of 0/0, Graaz is essentially providing it with a +5/+3 buff, on top of the counters the card gains as it enters play. Trample also allows the serpent to push damage through.
If you’re feeling particularly devilish you can even include a few infect cards like
Plague Myr

{T}: Add {C}.
and
Ichorclaw Myr

Whenever this creature becomes blocked, it gets +2/+2 until end of turn.
. Being buffed to 5/3 means with your commander in play means that these cards can finish off any opponent in two hits.
Quirks of a Colorless Commander

One of the most notable things about Graaz is that it is a Colorless card. Colorless Commanders present an interesting deckbuilding challenge as they significantly limit the cards you can use. While this may seem like a negative thing it also presents an inviting challenge, asking you to make the best deck possible out of a limited pool of cards. In the words of Magic’s chief designer Mark Rosewater, “restrictions breed creativity”.
Your removal options are highly limited, and you’ll need to rely on cards like
Meteor Golem



Colorless decks have their own basic land type in
Wastes


{4}, {T}: Target creature can't be blocked this turn.
,
Thespian’s Stage

{2}, {T}: This land becomes a copy of target land, except it has this ability.
, and
Reliquary Tower

{T}: Add {C}.
. In most decks, the colorless mana they generate is a downside. In colorless decks, however, these cards are just as good at generating mana as your Wastes once they are in play.
You also have the option of including the famous “Tron lands“:
Urza’s Mine


{7}, {T}: Create a 2/2 colorless Assembly-Worker artifact creature token.
, and
Urza’s Power Plant


Metalcraft — {T}: Add {C} for each Urza's land you control. Activate only if you control three or more artifacts.
. These lands can generate colorless mana incredibly quickly if they are all in play together, enabling you to race Graaz out. Just make sure you don’t include
Command Tower

Conclusion
There are many popular colorless commanders. The Eldrazi titans are probably the most famous, although
Emrakul, the Aeons Torn

When you cast this spell, take an extra turn after this one.
Flying, protection from spells that are one or more colors, annihilator 6
When Emrakul is put into a graveyard from anywhere, its owner shuffles their graveyard into their library.
is banned in the format. EDHREC data indicates that
Kozilek, the Great Distortion

Menace
Discard a card with mana value X: Counter target spell with mana value X.
commands over 5000 decks, as a giant 12/12 which lets you draw a huge number of cards as it enters play it’s easy to see why.
Traxos, Scourge of Kroog

Traxos enters tapped and doesn't untap during your untap step.
Whenever you cast a historic spell, untap Traxos. (Artifacts, legendaries, and Sagas are historic.)
is another popular choice, with over 2000 decks to its name. Even the very recent card
Liberator, Urza’s Battlethopter

Flying
You may cast colorless spells and artifact spells as though they had flash.
Whenever you cast a spell, if the amount of mana spent to cast that spell is greater than Liberator's power, put a +1/+1 counter on Liberator.
which debuted in The Brothers’ War already leads more than 1000 decks.
Whether
Graaz, Unstoppable Juggernaut

Juggernauts you control can't be blocked by Walls.
Other creatures you control have base power and toughness 5/3 and are Juggernauts in addition to their other creature types.
will rise up to join these titans and become a popular colorless commander for the ages, or will eventually peak and drop off in popularity is an open question. One thing is for certain though, Graaz is certainly off to a promising start.
