Introduction to Budget Mech Warrior

Mech Warrior is a tempo/aggressive deck possible thanks to new cards from The Boomsday Project. The intended use of this deck is to complete Warrior quests and grind Warrior wins for the golden hero on a budget, as top tier Warrior decks are all very dust expensive and look vastly different from this. While I wouldn’t recommend this over similar decks from other classes, it borrows a lot of strengths that Paladin versions of this deck have thanks to a lot of its best tools being neutral. In a similar vein, spending dust on this deck will not be a waste, as you can then use most of these cards in other classes (mostly Paladin). The reason aggressive Warrior decks aren’t top tier is largely due to the irrelevance of the Warrior hero power in decks like this one. If you’ve played Hearthstone as recently as last year, you know that aggro Warrior decks have been some of the most oppressively powerful decks the game has ever seen, but Warrior had two things in the past that it doesn’t now: Sir Finley Mrrgglton and pre-nerf Fiery War Axe. Sir Finley solved the irrelevant hero power issue and Fiery War Axe at 2-mana was a contender for the most busted aggro card in Hearthstone’s history.

Rastakhan’s Rumble Update

This deck lost one of it’s best tools with the nerf to Giggling Inventor, but with Rastakhan’s Rumble it gained something aggressive Warrior decks have had in a long time: cheap removal. Devastate, while no 1-cost Execute, helps your small minions trade up efficiently.

Budget Mech Warrior Mulligan Guide

More important than anything else is playing a minion on the first turn. Just about any will do, but as an aggro deck it is essential to have the earliest possible pressure. Every 1-mana minion in this deck can be kept in your opening hand, but if you have options Dire Mole and Eternium Rover are probably the better ones as they have the highest stat value.

If you already have a 1-mana minion, then Upgradeable Framebot and Dire Wolf Alpha are good to keep. You can keep a 3-mana minion with the coin, but you really want to use the coin on turn 4, as we’ll get to a little bit later. You can and should keep a 3-mana minion if you already have a 1 and 2-mana minion.

Budget Mech Warrior Play Strategy

This deck plays similarly to current aggressive Paladin decks: gain board control early and solidify it with powerful 5-mana cards. With decks like this in general, but especially with this one, you hope to never use your hero power.

First, you want to curve out. Keeping a 1-mana minion is essential, and ideally you would follow that up with a 2-mana or two 1-mana minions the next turn. This is an aggressive deck, and as such you want to have a good reason to trade your minions rather than damaging your opponent’s hero. Think about the worst case scenario if you leave an opponent’s minion on board, and whether or not it matters. For example, a Silver Hand Recruit isn’t often threatening on turn 2, but a couple of them leading into your opponent’s 5-mana turn will allow them to play Level Up!.

Frothing Berserker is probably the most powerful card in this deck, and is one of the best reasons to trade with your early minions rather than just attack the opponent’s face. Not only will trading protect your Frothing Berserker, but each trade increases its attack by two permanently. If left unchecked, Frothing Berserker can get out of control quickly and end games early on.

The strongest plays in this deck happen at five mana for the most part, and as such you want to save your coin for turn four, unless it will cost you tempo. The exception to this is if you’re holding Vicious Fledgling. Vicious Fledgling has what might be the highest snowball potential in the entire game, so against an opponent that isn’t likely to have an answer, if you coin it out on turn two it’s generally right to do so. When Adapting, prioritize Windfury first. Vicious Fledgling gets to Adapt every time it attacks, so getting to attack twice makes it snowball twice as fast. After that, you want survival > attack value. Things like Stealth, +3 health, Divine Shield, and “can’t be the targeted by spells and hero powers” (I really wish they would make a keyword for that effect) help keep Fledgling on the board, which results in more Fledgling attacks. When these are not available, or if you have enough of them, then you start to want +3 attack and +1/+1. Taunt, Poisonous and Deathrattle: Summon two 1/1 plants have their uses but they are few and far between, so it’s better not to take these if you can help it. When presented with these three options, it is best to go with Deathrattle most of the time.

In a perfect world Kor'kron Elite will go directly to your opponent’s face, but it can also be handy to trade with if you’re desperate to remove something.

Turn five is when this deck really shines thanks to Fungalmancer and Wargear. Fungalmancer is one of the strongest aggro minions currently in the game, because it turns unimpressive boards into real threats. Wargear is strong for a similar reason, and is the big payout for playing all the Mechs in this deck. To be powerful, both these cards require you to have something on the board already leading in to the turn you play them.

Battle Rage can be handy to keep you from running out of steam. As long as it doesn’t cost you a lot of tempo, it’s best to play this as soon as it will draw you two or more cards. This deck does not include the self-damaging cards that other decks utilizing it have in the past, but most of the earlier minions of the deck have high health. You can trade these early minions in a way that they survive with damage in order to get decent value from Battle Rage.

Budget Mech Warrior General Replacements

Aggressive Warrior decks are not very strong right now, and thus this deck does not translate into a meta warrior deck. This deck was designed with the intent that most of the cards you would need to craft for it can be used in parallel decks in other classes, so that is where you would make use of them outside of completing your Warrior quests. However, there are a few things you could change about this deck to make it better, if you happen to have the cards.  These replacements will have use outside of the Warrior class, but should not be crafted if you only intend to use them in this deck.

  • Prince Keleseth – Is easily the most powerful upgrade you could make to this deck. Current 2-mana minions aren’t very strong and removing them from the deck entirely is a big benefit. Saronite Chain Gang is already strong in that it sets up nicely for Fungalmancer, but it’s even better with Keleseth because it effectively receives his buff twice. Keleseth is a strong component of many other aggro decks (and even some control decks) which makes him a safe and powerful card to prioritize crafting.
  • Argent Squire and a second Fire Fly – Good early game minions that can substitute for other cards if you are missing them, or can replace 2-mana minions if you add Keleseth.
  • Woodcutter's Axe – It’s no pre-nerf Fiery War Axe but a 2-mana 2/2 weapon isn’t awful. The effect on the card won’t be relevant in this deck, but weapons with this stat value have been excellent aggro cards in the past (albeit they always had an upside). This is probably the best replacement for Battle Rage if it’s not working out for you and you don’t own Keleseth.
  • Void Ripper – Makes it easier to trade into Taunt minions with high health, and turns your high health low attack minions into big threats.
  • Nightmare Amalgam – Usually better than Harvest Golem. Don’t craft it, just replace Golem with it if you already have it.
  • Replicating Menace – After Wargear, this is probably the most aggressively strong Magnetic minion that Warrior can use. Again, it’s not worth crafting but if you happen to have it already then it fits into the deck well, especially if you have extra room from adding Keleseth.
  • Zilliax – This one is a maybe. Not as aggressive as other cards at its cost, and there are already plenty of 5-mana minions in the deck. It does add another good Magnetic minion to the deck to take advantage of all the Mechs in it.
  • Leeroy Jenkins – Leeroy Jenkins is the second strongest Legendary you could add to the deck (after Keleseth). He offers significant burst damage for the cost, and will help close out a lot of games like not much else could. Arcanite Reaper might be just as or even more powerful as a 1-of in this deck, considering it isn’t running any other weapons. With Arcanite Reaper you can burst for 5 one turn, and threaten to do the same the turn following without giving your opponent any 1/1 whelps.

    6 games in a row, 6 brutal loss in a row…absolutely NO CHANCE even in casual…something is missing here, maybe Mortal Strike. I´ll try both Battle Rage out, 2x Mortal Strike in…Otherwise, i think it will be still crap…

      Sure, maybe take out a Giggling Inventor, there’s a lot of Mossy Horror going around to counter it.

    Hello, thanks for this deck, I’ve crafted a few things, added Dr Boom and about to try it out. I just wanted to ask if Beryllium Nullifier or a Brawl/Reckless Flurry (my Warrior epics) or a Gluttonous Ooze could be useful, I had it left from my Quest Warrior deck.

    Is there any chance you could make a budget warrior deck centered around Dr Boom mad genius pls if that would even be a good idea. Thanks.

      Shield Slam, Reckless Flurry and a Dead Man’s Hand would be decent epics to add in if you have them. Also Blood Knight is bonkers right now because of Giggling Inventor. I don’t know if it’s worth it in a deck like this but maybe.

    What about Dr.Boom I recently packed him. Can he be used in this deck? If so what other cards should be played with him

    • Martian - Author
      August 13, 2018 at 8:13 am

      I suppose you could, he’d give you some late game value. Maybe take out a battle rage for him. Try it out!

      If you’re interested here’s a decent budgety control deck based around Dr.Boom.
