In this guide, we will cover all the Mech minions and how they go in the overall mech comp. We will go into detail for each minion and explain a bit about how they interact with other mechs, as well as how powerful they are in the current meta. There won’t be any specific builds as that is all explained in our full Hearthstone Battlegrounds strategy guide. In this format, go over all the mechs try to separate them from the final build, and explain them in terms of game progression.
Tavern Tier 1
Annoy-o-Tron
Annoy-o-Tron isn’t really a must-pick at Tavern tier 1, but he does have Divine Shield and Taunt, which can be useful as the game develops. He is especially good if you have something like a Pointy Arrow to enhance his power and make use of his Divine Shield.
Cord Puller
Similar to Annoy-o-Tron, this minion is one of the rare ones that has Divine Shield and the start and is considered a good early-game pick because the Divine Shield + the Microbot from the Deathrattle are annoying to deal with. Definitely one of the strongest tier 1 minions as it basically has 3/3 and needs to be hit 3 times.
Tavern Tier 2
Kaboom Bot
Time to blast things in Battlegrounds! Kaboom Bot is not the strongest minion in the Tavern for sure – but he is the most fun one! Jokes aside, Kaboom Bot is pretty strong in the begining as his Deathrattle can pretty much kill most of the tier 1 and tier 2 minions. Furthermore, you can enhance his ability by Titus and/or Kaboom Bot Portrait Lesser Trinket . This mechanic is not the strongest one in the game – but the fun is guaranteed when watching things explode on the board.
Ancestral Automaton
In the beginning of Season 8, Ancestral Automaton was everyone’s favorite minion as it scaled like crazy. He has been nerfed several times now but is still a pretty strong minion. Note that Reborn counts as summon as well so you can pair this minion with Prosthetic Hand. There are several Trinkets that work well with this ability too so sometimes he can even be your key minion.
Lullabot
Picking up Lullabot in the early stages is kinda awkward. On the one hand, you think that it is good because it will gain stats over the next several turns, but losing that one spot for an actual minion is sometimes bad because you can’t really sell the attached Lullabot. Nevertheless, it is a fine play to attach it to a Divine Shield minion early on, but it’s not as strong as it seems.
Tavern Tier 3
Accord-o-Tron
Probably one of the most important Magnetization in the game. Picking up this minion at Tier 3 is almost never a mistake because it’s just good value. If you happen to get a few of these with stuff that generates Magnetization minions, you are on a good path to victory. The reason for this is that Mechs don’t really have that many resources as everything revolves around attaching stuff and full commitment to specific units. A few Accord-o-Trons can make your game x10 times smoother with the extra gold each turn, especially if you have Polarizing Beatboxer and the attachment doubles.
Deflect-o-Bot
Deflect-o-Bot has been known as the “main minion” that carries the game and for a good reason. The ability that grants him, Divine Shield, every time you summon a mech is extremely annoying to deal with, especially if the RNG is on Deflect-o-Bot’s side. He can sometimes gain 3, 4, or even 5 times Divine Shield in one if you have Deathrattles that summon Mechs (Reborns).
Annoy-o-Module
Annoy-o-Module is one of the key magnetizations because of its Divine Shield + Taunt property. Basically, you can place it on everything except Deflect-O-Bot, since you want to force aggro away from them in order for them to regain Divine Shields. The rest is pretty self-explanatory. One thing to note is that you can cast it on Foe Reaper 4000 (because he naturally doesn’t have Divine Shield and really needs it), and then find Tricky Trousers in order to remove the Taunt from it.
Tavern Tier 4
Prosthetic Hand
The newest addition in Season 8 is Prosthetic Hand – an undead mech (how is that even possible?) that will give Reborn to your minions. This is your main defensive minion as you want to have as many reborns as you can so that Deflect-o-bot can renew his Divine Shield once a reborn occurs. Try to have at least one Reborn minion without Taunt so that when your taunt minions die, the enemy can hit Deflect-o-bot and then the remaining minion with Reborn.
Grease Bot
Grease Bot is … as the name suggest, a sluggish minion. Sure, he will give you some stat buffs but those are usually extremely slow compared to other things that you can get. You will still probably need Beatboxer in order to win, so don’t spend gold on refreshing and looking for Grease Bot – if you can, get him early on, if not that’s fine as well, keep playing.
Utility Drone
This minion is where your late game starts to develop. Utility Drone will buff up your Mechs a lot, especially once you get several magnetizations on your mech, and if you happen to find Drakkari Enchanter. In the mid-game, around Tavern Tier 4, where your army is probably still mixed, and you don’t really have much magnetization, Utility Drone isn’t anything special. But, in the late game, your Mechs will gain more and more attachments and this minion will ensure your board doesn’t fall off.
Tavern Tier 5
Clunker Junker
Clunker Junker is just awesome! There are 4 Magnetizations in total (Gold, Lulabot, Divine Shield, Reborn) and this guy will offer 3 of them to you. This means that you can, with 75% certainty, cast Divine Shield or Reborn on a minion that needs it. Furthermore, you can make a whole build focusing on Clunker Junker if Murlocs are in play and if you can get Bran Bronzebeard.
Charging Czarina
This minion has nice tempo, as well as some late-game stat gain. The logic is pretty straightforward: You will have a lot of Divine Shields, and casting a few Spells for the Attack gain is a very good mechanic. The best combo here is to also have Whirling Lass-o-Matic which will provide you the spells that will work with Charging Czarina. All in all, a good balanced minion.
Scrap Scraper
Scrap Scrapper is on okey-ish mech minion that won’t be a game changer. It’s pretty much a tempo minion as you will get one (or two with Reborn) Magnetization minions per turn but other than that, he doesn’t do much. You can’t pair him with Titus as he is your only Deathrattle minion so that’s why he is in such a weird spot in the current game meta.
Support System
While this minion is Duos-Only, and we mention him in our Hearthstone Battlegrounds advance duos guide, we will mention him here, since he is a mech after all. He is just a very good support minion that is used for the “supporting” player to provide permanent Divine Shields on their partner’s board, which is just extremely powerful.
Tavern Tier 6
Foe Reaper 4000
At first glance, this is a simple minion that has Cleave and some decent stats, but the real complication and power lies in the magnetization part. As we already mentioned, you should get a Divine Shield on Foe Reaper for Annoy-O-Module and remove the Taunt with Tricky Trousers. Moreover, it’s very powerful to find a Windfury for him, most likely from Mecha Jaraxxus. Buffing him additional with more magnetizations and Utility Drone, you can see how Foe Reaper 4000 can carry the whole game.
Polarizing Beatboxer
Polarizing Beatboxer should be your top priority in the mid-late game. The copying of magnetization is very powerful, and getting a few Accord-o-Trons is very good for your economy since you will replicate it on Polarizing Beatboxer, once you attach it to another mech. This applies to all other magnetizations and combined with Utility Drone, you can see how Polarizing Beatboxer poops off in the late-game.
Whirling Lass-o-Matic
Whirling Lass-o-Matic is one of the best “resource-gaining” minions. It almost guarantees you get at least two random spells after each battle, and it has decent stats with Divine Shield and Windfury. It can also just be a good standalone resource-farming minion that you will later sell if you happen to shift builds. All that said, do note that it’s extremely RNG-based, since you can get everything from Pointy Arrow to something like Eyes of The Earth Mother, which is obviously wildly different.
Tavern Tier 7
The Boommobile
While you won’t see this mech in most games (only with Thorm, Stormlord), it’s worth mentioning him. As you can see, he is essentially the all-encompassing ultimate magnetization minion that grants a lot to its host. The obvious choice to cast it on is on Foe Reaper 4000. That said, he is pretty underwhelming for a Tier 7 minion, especially if you compare it to some other game-changing ones like Champion of Sargeras.
