A little bit ago I covered how you can fight against Aggressive decks, and how you can slow down lists looking to take you down before you have the chance to get going. In this article we'll be covering the other half of the equation, in sideboarding against slower decks looking to control you out.
With access to strong control tools, lockdown pieces, consistent value generation, attrition tools and more, playing against control can feel overwhelming at times, but there's a myriad of ways to approach these matchups, and that flexibility is helpful when it comes to preparing your sideboard tools against them. I've grouped this into three methods that I call Going Over, Going Around, and Going Through, let's break down what each of these means.
Going Over - (More Control Power)
A cornerstone of control decks is their access to two things: strong interactive tools, and strong value tools. The interactive tools are how they stop faster decks in their tracks, while the value tools are how they attain more strength in the late-game to overtake opponents. When it comes to sideboarding, you can bring in more of this control power of your own, giving you the ability to beat them at their own game.
Going Around - (Additional Burn/Damage)
When you're playing an aggressive deck against a control deck, your general goal is killing them as soon as possible. Sometimes when it comes to post-sideboard, the best way to do that is to just lean into that strategy by pulling in even more damage to try to push in enough damge. Burn damage can be especially useful with many top control decks having ways to stop Warriors.
Going Through - (Hate Pieces)
Just like with any other deck, control decks have certain synergies that the rely on for their control tools to function. For example, Gaia relies on Eradication effects for a large variety of triggers in her deck, aswell as Perish abilities for a lot of her Card draw and Removal, such as with Jasmine, The Unstoppable Water Beauty, and Latarr, The Daughter Of Destruction. For Seraphim, Michael relies on Holy Counters both to keep his board-state firmly in play, while also being used to fuel abilities of cards like Kabshiels' Favours For The Seraphim and Bow Of The Archangel. As such, many of the hate effects that can be used against faster decks can also play double duty against some control matchups.
As mentioned, one way to try beating control is by Going Over - beating them at their own game. Control decks are packed with value tools and interaction tools, and leaning into one of these categories can give you the power to either keep up with them, or stop them from pulling ahead in the first place.
Interactive tools like Pandora's Box and Fandorian Ferocity give you great ways to directly attack their Fortified cards, while Dismantle and Seal let you target the most crucial ones to negate, like Mists Effects that would otherwise buy them a turn. While you certainly can just run enough Interaction to brute force through opposing interaction *cough cough*, even just a few extra pieces in the sideboard can be enough to push through their defenses.
When it comes to Value, one advantage you can have in control matchups is that they don't usually have easy access to early aggression. As such, some otherwise way too greedy cards can become a lot better. Whether they have an expensive Bloodbourne cost, or rely on going past turn 3, these pieces can offer a nice little shot of value to keep up with the card advantage that control decks generate. Against Aggro, a heavy Bloodbourne fortified that only draws cards might be a death sentence, but against control it might just be enough resources to let you close out the game.
When it comes to trying to best kill your opponent, sometimes the best plan is doing just that. It's important to note that most control decks have some incredibly strong ways to deal with Warriors such as:
Gaia - Giving Warriors Blockade
Mal'ady - On board negative Bestow effects
Michael - Helios & Luna and Holy Counters
Onoskelis - Warrior stealing effects
With this, having additional burn effects in your sideboard can be incredibly helpful to push in extra damage past the anti-Warrior control tools that the control lists have access to. Repeatable Burn effects like Controlled By The Chaos Divine, Majik Mask - Three Eye Dark, and Betrayal From Within can especially be powerful when games go longer, and you get to keep putting the hurt on.
With many Control Decks, there are good hate cards available to shut down parts of their deck, just like with Aggro Decks. I'd note that this strategy is specifically useful if you pay attention to play/draw, as many of these more proactive measures are much better when deployed on the Draw. Concrete Catacombs and Majik Void Collapse are incredibly useful cards at any point in a game, but they're at their best when they're being played before or on your opponent's first turn, doing the most to limit what they have access to when setting up.
With the huge amount of Variety here it's important to consider the various parts of a deck and what they're weak against.
For example, Gaia focuses significantly on Eradication synergy pieces, so Concrete Catacombs is a great piece against her. What Catacombs doesn't stop however is some of her strong draw and removal pieces in Jasmine, The Unstoppable Water Beauty and Latarr, The Daughter Of Destruction. As such, you might also want to prepare tools to deal with her strong warrior perish effects. This also gives you a ton of flexibility when building out your sideboard, as even if you can't access a certain sideboard card like Concrete Catacombs or Majik Void Collapse, there are other angles available to hate out a variety of decks.
There are also some other smaller inclusions that may take some attention. For example, Twilight Princess Hyacinth is an incredibly strong control piece that's made her way into a large number of decks. Depending on your main-deck tools, you might need to have some sideboard cards just for her, like Eon, The Timeshift Warlock or Sunrise, Consumed By Courage. That being said, there are also some non-conventional ways to deal with Hyacinth such as with Twilight Rose that might be better suited to your sideboard, or already be present in your maindeck.
All this information should hopefully help to evaluate why a card might be good in your sideboard, and how it can keep you in the running against the decks trying to slow you down. To actually help with picking out sideboard options however, here's a quick list of some great options to beat out some of the best decks in the metagame, to help build a base for your sideboarding.
