Chaos Reigns is the loudest deck in Planechase Anthology's lineup, a five-color pile built entirely around chaining free spells off of Cascade.
Where the other three decks in the box each stick to two colors, Chaos Reigns goes all five, embracing exactly the kind of unpredictable, multi-spell turns its name promises.
Its headline card, Maelstrom Wanderer, was a genuinely new printing at the time, a mythic that quickly became a defining piece of Commander decks well beyond this preconstructed box.
This guide covers how the deck's Cascade engine actually works, what makes Maelstrom Wanderer the centerpiece, and where to take the deck once you start upgrading it.
Cascade lets a spell reveal cards from the top of your library until hitting a cheaper nonland card, then cast that card for free before continuing on with the original spell.
Chaos Reigns leans entirely into this mechanic, filling its spell slots with Cascade triggers so that a single card in hand can realistically produce two or more spells' worth of value in one turn.
Maelstrom Wanderer, the deck's mythic rare, casts two spells off the top of your library for free every time it attacks, on top of granting haste and trample to your whole team.
It was one of several cards in Planechase 2012's decks printed for the first time here, and it has since become a defining Commander general built entirely around cascading value on attack.
Running all five colors gives Chaos Reigns access to the widest possible pool of Cascade-friendly spells, since restricting to fewer colors would meaningfully shrink what the deck can hit off a cascade trigger.
The tradeoff is consistency: a five-color manabase asks more of your land drops than a two-color deck, which is part of why this remains the box's most build-around, higher-variance deck.
Games with Chaos Reigns tend to swing hard in one direction once a big cascade chain connects, turning an otherwise quiet board state into a sudden multi-spell blowout.
That volatility is the entire appeal: this is the deck built to embrace Planechase's chaotic multiplayer format rather than fight against it.
Wizards' own coverage of the box suggested adding Rashmi, Eternities Crafter, a card that also rewards casting spells off the top of your library, as a natural fit alongside the deck's existing Cascade package.
Any additional Cascade spell, or any card that further rewards playing extra spells in a turn, slots naturally into what Chaos Reigns is already trying to do.
Compared to Night of the Ninja's evasive tempo plan or Savage Auras' incremental value engine, Chaos Reigns is the most explosive and least predictable of the four decks out of the box.
That makes it a strong pick for players who want maximum table chaos in a Planechase game rather than a tighter, more controlled strategy. Keep the deck and its planar cards together in a deck box between games.
A five-color deck lives or dies on its fixing, so prioritizing dual lands, mana rocks, and any land that can produce multiple colors is a more impactful upgrade than adding more spells early on.
Trimming the deck's color requirements slightly, rather than forcing every spell to demand a specific color at a specific turn, also smooths out draws without sacrificing much of the deck's overall power.
Even a modest handful of upgrades to the mana base tends to matter more here than in the box's two-color decks, since a five-color deck has proportionally less room for error on any given turn. Prioritize fixing before adding more spells whenever you have a choice between the two, since a stronger spell you cannot reliably cast is worse than a weaker one you can.
All five colors, built around the Cascade mechanic.

Yes, it was among the cards printed for the first time in Planechase 2012, reprinted here in Anthology.
Wizards' own coverage suggested adding Rashmi, Eternities Crafter for more free-casting synergy.
Chaos Reigns is the easiest of the four decks to take straight from the box into a full Commander build around Maelstrom Wanderer. Keep it protected in premium card sleeves once you start shuffling it regularly.
If five-color chaos sounds appealing, this is the deck in the box worth building around first.
