Deck Name: One Army to Rule Them All

Format: Legacy
Deck Type: Mechanic-Based Control
Deck Theme: Amass Legion Engine – Single Orc Army Scaling
Colors: Blue-Black-Red (Grixis)

-----------------------------------------------------------------------------------------------
Description

"One Army to Rule Them All" is a Legacy mechanic-based control deck that overwhelms the battlefield through a single, ever-growing Orc Army token. By utilizing Amass cards such as Swarming of Moria, Foray of Orcs, and Treason of Isengard, the deck transforms every spell into a moment of growth, forging one unstoppable threat from the fires of Grixis spellcraft.

The control elements allow you to dictate the pace of the game, ensuring that the Army grows without interruption. Interaction such as Fatal Push, Counterspell, and Lightning Bolt keeps opposing threats in check while your Amass engines escalate the pressure. With supporting tools like Ledger Shredder, The Meathook Massacre, and The One Ring, the deck maintains card advantage and stability until the Orc Army reaches critical mass.

This deck thrives in multiplayer and 1v1 Legacy, excelling in matchups against aggressive and midrange decks. With a combination of removal, counterspells, and Amass scaling, the deck steadily builds toward a decisive and overwhelming victory.

-----------------------------------------------------------------------------------------------
How to Play

Early Game:
Use Fatal Push and Lightning Bolt to neutralize early threats.
Establish card draw and filtering with Brainstorm, Ponder, and Ledger Shredder.
Deploy Swarming of Moria early to form the first Orc Army and gain Treasure acceleration.

Mid-Game:
Control the board while growing your Army using Treason of Isengard and March from the Black Gate.
Maintain pressure with Orcish Bowmasters, which synergize naturally with the Amass plan.
Leverage Narset, Parter of Veils to restrict opposing draw engines and secure card advantage.

Late Game:
Scale your Orc Army through repeated Amass triggers from Foray of Orcs and Book of Mazarbul.
Equip Shadowspear to turn your massive token into a lifelinking, trampling finisher.
Use The Meathook Massacre to stabilize your life total and weaken opposing boards.
Refuel with The One Ring to ensure inevitability and maintain tempo through long games.

Ideal Opening Hand:
A strong opening hand should include:
Two lands (preferably with two colors represented)
A piece of interaction (Fatal Push, Lightning Bolt, Spell Pierce)
A cantrip (Brainstorm, Ponder)
An early engine piece (Swarming of Moria, Ledger Shredder, or March from the Black Gate)

Mulligan hands that lack mana consistency or have no early interaction.

How the Mechanic Works

Set Up the Engine:
Begin by establishing an Orc Army token through Swarming of Moria or Treason of Isengard.
This token serves as the single focal point of the deck’s win condition.

Scale Through Spells:
Each Amass effect adds counters to the same Army, causing exponential growth.
Cards like Foray of Orcs serve dual roles: removal and significant Army escalation.
March from the Black Gate and Book of Mazarbul provide repeatable or combat-based Army upgrades.

End the Game:
Once the Orc Army reaches a dominating size, Shadowspear converts it into a lifelinking, trampling force.
The One Ring ensures continued card flow, preventing the deck from running out of resources as you close the game.
The combination of control elements and a single massive threat forces opponents into an unwinnable position.

Play Like a Pro – 5 Tips for Mastering the Deck

Protect the Army’s growth engines.
Counter threats that disrupt Swarming, Treason, or March—these matter more than stray creatures.

Sequence Amass triggers carefully.
Combining Treason into Foray into Book-based combat grows the Army far faster than isolated plays.

Use Shadowspear only when it will swing the game.
Equipping too early wastes mana; equipping too late may miss lethal.

Leverage The One Ring for inevitability.
Deploy it when hands run low or when you need unstoppable card flow.

Keep your hand full and options open.
Blue cantrips give flexibility—use them to find either interaction or Amass pieces depending on the match.
