Battlegrounds Compositions

When and How to build Mechs in Battlegrounds

Compositions are one of the toughest aspects of Battlegrounds. We hope our guides to Mechs & all other tribes help you learn.

A common problem that struggling players have is figuring out for what cards they should be looking. One of my tips on how to improve in Battlegrounds is knowing what minions you should be searching for so you know how to spend your gold. But before you can do that, you have to know the optimal builds that can win you the game. Here are the optimal end game builds for Mechs as of Patch 21.2. For our complete Battlegrounds composition series, click here!

There are five builds you can do with Mechs now in Battlegrounds! 3 of them require Deflect-o-Bot, one is based around Kangor’s Apprentice and Deathrattles, and a new one from Patch 21.2 is a build revolving around MechanoTank.

NOTE: While not explicitly stated, Replicating Menace will always be implied to have on your mechs. As well, Refreshers are any cards that spawn another mech when it gets destroyed.

When should you go for the Deflect-o-Bot build?

The correct answer is: once you find Deflect-o-Bot and the support cards. Many heroes utilize Deflect-o-Bot well and if you can get the right build, he will be quite a powerhouse. The three builds you can do with Deflect-o-Bot are known as:

Traditional Deflect-o-Bot Build

Mecherel Build

Taunt Comp Build

The keycards for all of these are Deflect-o-Bot and Grease Bot. The latter helps scale to the end game with our divine shield minions. Let’s discuss them one at a time.

Traditional Deflect-o-Bot Build

Mid Game Build:
Deflect-o-Bot | Deflect-o-Bot | Micro Mummy | Micro Mummy | Grease Bot | Grease Bot | Metaltooth Leaper

Common Late Game Build:

Deflect-o-Bot w/ Replicating Menace | Deflect-o-Bot w/Replicating Menace | Micro Mummy | Mecheral | Kangor’s Apprentice | Golden Grease Bot w/Replicating Menace | Divine Shield Taunted MechanoEgg

Keycard: Deflect-o-Bot, Metaltooth Leaper

This is a standard-looking Deflect-o-Bot build where you could not find the key cards to help you reach high into the late game. This is more of a midrange build where you are just trying to survive and make it to the top 4.

Mecherel Build

Mid Game Build:
Deflect-o-Bot | Deflect-o-Bot | Micro Mummy | Micro Mummy | Grease Bot | Grease Bot | Metaltooth Leaper

Common Late Game Build:

Deflect-o-Bot | Deflect-o-Bot | Taunted Divine Shield MechanoEgg | Mecheral | Another Divine Shield Minion or a Refresher | Golden Grease Bot | Divine Shield Taunted Mecheral w/ Replicating Menace

Keycard: Deflect-o-Bot, Mecheral 

Mecherel Build is really powerful with very difficult ways to properly counter. Windfury and Unstable Ghouls can help but if your opponent knows what you are up to, there can be ways to get around that.

Taunt Comp Mechs

Mid Game Build:
Deflect-o-Bot | Deflect-o-Bot | Micro Mummy | Micro Mummy | Grease Bot | Arm of the Empire | Arm of the Empire

Common Late Game Build:

Micro Mummy | Kangor’s Apprentice | any Taunted Divine Shield Mech | Either Mecherel, another divine shield taunted minion or another refresher | Taunted Deflect-o-Bot | Taunted Deflect-o-Bot | Golden Arm of the Empire

Keycard: Deflect-o-Bot, Arm of the Empire, Defender of Argus, Annoy-o-Module

Taunt Comp is the fastest way to give Deflect-o-Bot attacks, making them scale at a high rate. However, it is the build with the most weaknesses. It is weak against Deflect-o-Bot being attacked twice, cleave, and minions with special effects that deal damage indirectly such as Soul Juggler, Red Whelp, and Prestor’s Pyrospawn.

When should you go for Deathrattle Mech comp?

The keycards for this build are Kangor’s Apprentice, Baron Rivendare, and deathrattles such as Omega Buster. The Deathrattle Mech comp is much more difficult to pull off as it requires numerous high-tier cards. While Deflect-o-Bot can be found much earlier, this is a build that does not require much scaling to accomplish. Once you have the right cards, you can use the build’s innate strength to carry you. This is the only build that does not want you to use Replicating Menace.

Mid Game Build:
Deflect-o-Bot | Pupbot | Pupbot | Harvest Golem | Kangor’s Apprentice | Baron Rivendare | Annoy-O-Module

Common Late Game Build:

Omega Buster (Taunted) | Deflect-o-Bot | Omega Buster (Taunted) | Foe Reaper | Deflect-o-Bot | Kangor’s Apprentice | Golden Baron Rivendare

The plan for this build is to use the power of Omega Buster to do a wide buff to your board. It becomes the key reason why Kangor’s Apprentice is incredibly strong right now. Try combining Omega Buster’s strength with Deflect-o-Bot, Omega Buster, or Foe Reaper. Be careful: Do not triple your Kangor’s Apprentice. Since it becomes “Summon the First 4 Mechs destroyed”, it is more effective to have two of them instead of one Golden. That way you get more chances to respawn more Omega Busters.

Alternatively, you can do a build like this:

Golden Monstrous Macaw | Mecherel | Foe Reaper | Deflect-o-Bot | Omega Buster | Baron Rivendare | Annoy-o-Module

It is very similar to the Monstrous Macaw and Goldrinn, the White Wolf, build for Beasts, except you’re using Omega Buster and Mechs. The principal is still the same, but do not put Replicating Menace or Kangor’s Apprentice in your build.

When should you go for a MechanoTank build?

When you have no direction and just need to make it to the top four. This build will not get you first most of the time and is generally a desperate attempt to survive. It is very similar to Soul Juggler build but much more flexible since it does not require certain tribes for this build.

Mid Game Build:

Scallywag | Scallywag | Sewer Rat | MechanoTank | MechanoTank | Acolyte of C’Thun | Acolyte of C’Thun

Common Late Game Build:

Acolyte of C’Thun | Acolyte of C’Thun | Voidlord | Voidlord | Omega Buster | Golden MechanoTank | MechanoTank

MechanoTank build is completely new but works the same as Soul Juggler build. You want units that drop many respawned minions and have Taunt so you can proc MechanoTank’s avenge ability. The build is easy, especially since Omega Buster is optional but do not expect to get top victories with this build.
