Buy Arm for Battle on TCGplayer →Quick verdict
Arm for Battle is a voltron deck built around a cheap commander that draws cards. Wyleth, Soul of Steel costs three and draws a card for each Aura and Equipment attached to it every time it attacks, so a suited-up Wyleth refills your hand while it deals commander damage. The deck has good Equipment and a lot of cheap interaction, but it has almost no ramp, a mana base full of tapped lands, and several situational instants that rarely help Wyleth connect.
TurnZero HQ rates Arm for Battle a 2 out of 5 on difficulty and a 3 out of 5 on power, as it comes in the box. That is our editorial read, not an official Wizards rating. The full hundred cards are on the Arm for Battle decklist page, and every other precon we cover is on the precon directory.
How the precon plays
Wyleth, Soul of Steel is a three-mana 2/2 with trample. Whenever it attacks, you draw a card for each Aura and Equipment attached to it. With Bonesplitter and Swiftfoot Boots on it, each attack draws two cards, and it hits harder with every piece you add. Since it only takes 21 combat damage from a commander to knock a player out, a heavily equipped Wyleth can end games quickly.
The support pieces make the Equipment cheaper and faster. Sram, Senior Edificer draws whenever you cast an Aura or Equipment, Danitha Capashen, Paragon makes them cost one less, and Sigarda's Aid lets you cast Equipment at instant speed and attach it for free as it enters. Brass Squire attaches Equipment without paying equip costs, and Relic Seeker tutors one up once it becomes renowned.
The deck keeps Wyleth alive with Swiftfoot Boots , Mask of Avacyn , Timely Ward and protective instants like Valorous Stance and Boros Charm . Tiana, Ship's Caretaker returns Auras and Equipment to your hand when they go to the graveyard, which softens the blow when Wyleth dies.
What works out of the box
Wyleth, Soul of Steel ↗
Three mana with trample, and every attack draws a card for each Aura and Equipment attached to it.
Sram, Senior Edificer ↗
Two mana, and it draws a card whenever you cast an Aura, Equipment or Vehicle. With Wyleth, the deck rarely runs out of cards.
Sigarda's Aid ↗
Equipment attaches for free as it enters, and you can cast Auras and Equipment at instant speed. It skips most equip costs.
Blackblade Reforged ↗
Equip 3 to a legendary creature for +1/+1 per land you control. On Wyleth in the midgame, it is often +7/+7 or more.
Sunforger ↗
Gives +4/+0, and you can unattach it to cast a red or white instant from your library for free, like Boros Charm or Swords to Plowshares.
Swiftfoot Boots ↗
Hexproof and haste for equip 1. It protects Wyleth from targeted removal and counts as one more card drawn per attack.
What needs improvement
The deck has almost no ramp. Sol Ring and Boros Signet are the only mana rocks, and many of the lands enter tapped, including Boros Guildgate , Stone Quarry , Wind-Scarred Crag , Rupture Spire and Transguild Promenade . Voltron decks spend a lot of mana on equip costs every turn, so falling behind on mana means Wyleth attacks with fewer pieces. See how much ramp a Commander deck needs for a target count.
Several instants do not help Wyleth connect. Wild Ricochet and Dualcaster Mage need an opponent's spell worth copying, Word of Seizing and Master Warcraft are expensive one-turn effects, and Deflecting Palm and Dawn Charm only deal with a single source or a single combat. Those slots are better spent on ramp, protection and Equipment support.
Upgrade ideas
Each upgrade below starts from something the deck does poorly and says what a replacement card has to do. The cards named are examples, not the only answer: if you own something else that does the same job, or a newer printing does it better, it goes in the same slot. Make one change at a time and play a few games between them, so you can tell which change helped. The general method is in how to upgrade a Commander precon →
1. Add the ramp the deck is missing
Equip costs add up quickly, and two mana rocks are not enough for a deck that wants to cast Wyleth on turn three and equip it every turn after.
What to look for Two-mana rocks that make red or white, or Equipment that ramps when it attacks, so it also adds a card to Wyleth's draw trigger.
Cut, for example
Wild Ricochet Redirects and copies an instant or sorcery. It needs an opponent's spell worth stealing, which you can't plan around.
Dualcaster Mage A 2/2 with flash that copies a spell. In a deck with few big spells of its own, it is usually just a 2/2.
Add, for example
Arcane Signet ↗
Two mana, taps for red or white.
Talisman of Conviction ↗
Two mana, taps for red or white at the cost of 1 life, or for colorless with no damage.
Fellwar Stone ↗
Two mana, taps for any color an opponent's land could make. Usually red or white at most tables.
Sword of the Animist ↗
Two mana and equip 2: +1/+1, and it fetches a basic land whenever the creature attacks. On Wyleth it is ramp and a card each attack.
2. Untap the lands
The deck plays more than a handful of tapped lands, and two that make you pay one mana as they enter. Each one costs you an equip activation or a spell in the early turns.
What to look for Red-white dual lands that enter untapped. The land and mana base guide compares the main cycles.
Cut, for example
Rupture Spire Enters tapped and makes you pay {1} or sacrifice it. Command Tower and real duals fix just as well in a two-color deck.
Transguild Promenade The same drawback as Rupture Spire. It slows down two turns to fix colors a two-color deck rarely struggles with.
Memorial to War Enters tapped, and its land destruction costs six mana total. That mana is better spent on equip costs.
Add, for example
3. Make Wyleth harder to kill
When Wyleth dies, every Aura on it goes to the graveyard and the deck's draw engine stops. Permanent protection that also counts as an Equipment does two jobs.
What to look for Equipment or Auras that grant indestructible or hexproof, ideally ones that can come down at instant speed or attach themselves.
Cut, for example
Word of Seizing Five mana to steal a permanent for one turn. It rarely changes a game the way protection on Wyleth does.
Master Warcraft Four mana to control one combat. Clever, but it does not protect Wyleth or draw cards.
4. Find and equip Equipment faster
Wyleth's draw depends on how many pieces are attached, so cutting equip costs and finding the right Equipment early both mean more cards per attack.
What to look for Creatures that tutor Equipment, reduce equip costs, or draw when Equipment enters.
Cut, for example
Deflecting Palm Prevents damage from one source for one turn. It is a defensive trick in a deck that wants to be the attacker.
Dawn Charm A fog, a regeneration or a narrow counterspell. Valorous Stance and Boros Charm protect Wyleth more often.
Win conditions
The upgraded deck wins with commander damage. Cast Wyleth, Soul of Steel early, attach Equipment and Auras each turn, and attack to draw a card per piece. Blackblade Reforged , Sunforger and Bonesplitter add the power, while Fireshrieker , Temur Battle Rage or Sunhome, Fortress of the Legion gives Wyleth double strike for the lethal swing. The added ramp and protection let you equip more each turn and keep Wyleth on the battlefield long enough to deal 21.
Who should buy this precon
A good starter deck for voltron. The plan is easy to follow (put things on Wyleth, attack, draw), and every turn shows whether you are getting closer to 21 commander damage. Equip costs and sequencing take a little practice, and some opponents will focus their removal on Wyleth, so this suits a newer player who is fine with taking some risk on a single big threat.
