Commander is, at its heart, a game of calculated risk. We build decks to minimise variance, sculpt our hands, and smooth out our mana curves all in the name of consistency. But that doesn’t mean that we can’t enjoy the occasional commander that demands you embrace the chaos of the random roll and run a full-blown casino. Enter Mr. House, President and CEO.
At first glance, Mr. House looks like a fun, casual gamble. You pay four mana, tap him, roll a d20, and pray to the RNG gods. Roll a four or higher, and you get a 3/3 Robot token; roll a six or higher, and you get a Treasure token to boot. But if you think this deck relies on pure luck, you’re playing right into the casino owner’s hands. The secret to piloting Mr. House isn’t hoping for high rolls; it’s rigging the game so that the house always wins.
Through a mix of dice manipulation, token multipliers, and sacrifice-based burn engines, this Mardu build turns every roll of the dice into a localised mass-production crisis for your opponents. We aren’t just rolling for value; we are building an industrial army of Securitrons and buried treasure, all powered by the tap of a d20.
Yes, a d20.
To make Mr. House function, you have to throw out the idea of a “fair” die roll. The engine relies on high-density rolling and advantage mechanics that guarantee you hit that golden threshold of 6+ almost every single time. By including lots of cards that allow you to roll a d20, you’re already facing much better odds of getting that 6+, as compared to rolling the d6s that Mr. House’s inbuilt ability allows.
Cards like Wyll, Blade of Frontiers and Barbarian Class are the backbone of this strategy. By giving you advantage on your dice rolls (rolling two d20s and keeping the highest) they further shrink the odds of a miss. Suddenly, hitting a four or a six isn’t a gamble; it’s a statistical near-certainty. Upgrading Barbarian Class to level two even adds flat damage, turning your dice-rolling routine into passive board pressure.
There are a ton of cards in here to let you roll some dice. These include some pretty high-yield engines. Delina, Wild Mage offers an explosive, unbounded ceiling. Every time she attacks, you roll a d20 to clone a creature, and if you hit an 15–20, you roll again. Combined with Mr. House, a single attack step from Delina can trigger a cascade of Robot creations, extra dice rolls, and non-legendary copies of your best payoffs.
Finally, no discussion of this deck’s dice engine is complete without Vexing Puzzlebox. It builds counters equal to whatever you roll, triggering Mr. House along the way, before eventually cashing those counters in to tutor any artifact straight onto the battlefield. Whether that fetches a board-exploding Helm of the Host or an engine-defining Krark-Clan Ironworks, the Puzzlebox turns your luck directly into tutored lethality.
Once you’ve rigged the odds, the next step in the casino playbook is maximising the payout. Mr. House gives you a single 3/3 Securitron and a solitary Treasure token on a high roll. That is decent value, but in a four-player Pod, “decent” doesn’t close out games. To turn a trickle of tokens into a tidal wave, we run a terrifying suite of token multipliers.
Academy Manufactor is an absolute star in this deck. Whenever Mr. House attempts to create a single Treasure token, the Manufactor steps in and hands you a Treasure, a Clue, and a Food instead. Suddenly, a simple roll of six or higher isn’t just ramp; it is ramp, card draw, and life gain wrapped into one passive trigger. In all honesty, I do worry that this card falls slightly into the win-more category and will often avoid playing him because I’m just not in the mood to handle the board state he helps to create, especially once token multipliers are added to the mix.
When you pair this with Mondrak, Glory Dominus or Anointed Procession, the numbers scale out of control. One successful d20 roll explodes into four 3/3 Securitrons and eight assorted artifact tokens.
To keep this engine churning, we don’t rely on standard turn structures. Cards like Unwinding Clock, Sting, the Glinting Dagger, and Drumbellower untap Mr. House and your key mana rocks or dorks on every single player’s turn. By taking four activations per turn cycle, you turn the game into a relentless assembly line of cardboard metal.
Creating a massive pile of Clues, Treasures, and Securitrons is impressive, but you still need a way to liquidate those assets into player elimination. This is where our sacrifice engines and high-impact payoffs step into the spotlight.
Marionette Master turns your Treasure hoard into a lethal weapon. With her high base power (especially if fabricated with counters), cracking a few Treasures to fuel your spells or activate abilities drains your opponents’ life totals in huge, non-targeted chunks. They can’t block it, and short of split-second removal, they can’t stop it once the triggers are on the stack.
For pure mana efficiency and combo potential, Crime Novelist and Pitiless Plunderer act as the ultimate middle management. Every time an artifact or Treasure goes to the graveyard, Crime Novelist grows larger and refunds red mana, while Plunderer ensures you never run out of sacrifices. Combined with outlets like Jan Jansen, Chaos Crafter or Krark-Clan Ironworks, you can loop token creations and activations until the table is wiped clean.
And if your opponents manage to stall out your direct burn, Commissar Severina Raine provides the combat punch. Swinging with an army of 3/3 Securitrons while Severina drains the table for every attacking creature turns your token wide-strategy into an inescapable clock.
Piloting Mr. House is one of a really rewarding strategic experience. It balances the unpredictable thrill of high-stakes gambling with the cold, precise execution of an optimised engine deck. You get to throw hands full of dice, track dozens of tokens, and watch your opponents do the math on a board state that changes with every single roll.
There are occasions where the deck just fials do to… anything. These are pretty rare. The deck, once it gets going, it actually really strong and pretty consistent once you start rolling dice and generating Treasure tokens. It can steamroll pretty fast, and there’s nothing quite like flooding an opponent with Robot tokens! It’s a lot of fun, but shouldn’t feel oppressive towards your opponents.
I think, like several of my decks, that if I wanted to improve this signfiicantlky, it’s the landbase that really needs attention.
