In the past when sideboarding for the control matchup, you couldn't grab your copies of Chrome Mox fast enough. It made sense for that time, you wanted to be on a more consistent game-plan with more resiliency – this is where the "Grinding-Station" theory came from. That said, this plan is out-dated in today's metagame. With the printing of Search For Azcanta, the control decks have such a strong late game as they create actual card advantage instead of theoretical card advantage with Sensei's Divining Top. This creates situations where even multiple copies of Past in Flames isn't effective against their flurry of Flusterstorm, Surgical Extraction, Force of Will, and Snapcaster Mage.
Well, how do we beat that?
By going under them! This is where our good friend Chrome Mox comes back to the equation. These control decks are actually weakest in the set-up stage of the game, meaning that fast hands with a single piece of disruption are generally good enough to defeat these menacing control decks. Other than Search For Azcanta, there's also Counterbalance out of Miracles and Hymn to Tourach out of the black-based control decks.
An easy and effective way of playing around these cards is to simply combo off before they're relevant. With Hymn to Tourach based control decks, one strategy I personally like is playing out my artifact mana (Chrome Mox, Lotus Petal, and Lion's Eye Diamond) and then allowing the Hymn to Tourach happen. TES is a very threat based deck with typically 7-8 "tutor effects" to draw off the top of your library, allowing a lot of "I win the game" scenarios.
When sideboarding you should think of how your opponents are trying to combat you, for these matchups, all types of control decks are bringing in copies of Flusterstorm, Surgical Extraction, and Pyroblast. This is manageable, you can combat Surgical Extraction rather easily as it's not actually that good against TES (we don't really utilize Past in Flames as much as Ad Nauseam Tendrils). What you should do is sideboard in your copy of Tendrils of Agony because if the control player hits a copy of Burning Wish (with Surgical Extraction) that will leave you with Empty the Warrens as your win condition. This is an issue because Empty the Warrens isn't typically the strongest in these matchups due to cards like Terminus, Batterskull, Toxic Deluge and Marsh Casualties.
I've been trying to do something different recently when sideboarding against Blue and White based control decks. Instead of taking out copies of Chrome Mox or Ponder, I've been siding out all four copies of Rite of Flame! While it sounds a bit nuts I've put a lot of thought into it. By keeping Chrome Mox and Ponder in the deck you're keeping your threat density high while maintaining your speed. Rite of Flame is relatively low impact here and doesn't improve Ad Nauseam like Chrome Mox does. There's also a slight benefit to having less one casting cost cards in case of Counterbalance.
The last card to fend off would be Flusterstorm, which isn't always the easiest. Against the blue & white based control decks, cards like Xantid Swarm or even Defense Grid are very effective against this, but if you don't like these cards you can always attempt to overload on discard spells. I'm personally not a big fan of going over seven discard spells as you're only fighting them on one axis while they're combating you on several (the stack, graveyard, and permanents). In theory, discard spells can answer all of these, but in actual game play cards like Brainstorm or Snapcaster Mage can hide cards long enough to defeat you at an opportune time. Something like Xantid Swarm or Defense Grid can't be targeted by Flusterstorm and have a huge impact on the game. These strategies only work agains the blue & white based control decks, against the Hymn to Tourach based control decks I don't think permanent based answers that stop counterspells are effective. When the opponent has a solid mixture of discard spells and counterspells, it makes Xantid Swarm and Defense Grid rather embarassing. Not to mention the fact they're both answered by Kolaghan's Command.
The last way to fight back (blue & white based control decks) is to bring in answers for permanents, it doesn't matter if you're splashing green for Abrupt Decay or staying Grixis. You should bring in some sort of answer for Counterbalance, Ethersworn Canonist and the uncommon Meddling Mage. Against the Hymn to Tourach based control decks, if they play more than two copies of Leovold, Emissary of Trest I try to sideboard in a few answers as I don't want to be forced into an Empty the Warrens line if the situation doesn't call for one. If you don't understand why, please read the "Small Creature Combo" decks section for the answer.
