Hour of Devastation (HOU): Set Guide & Card List

Some sets arrive as an introduction. Hour of Devastation arrives as a reckoning. Released on July 14, 2017, this 209-card expansion is the second and final set of the Amonkhet block - and where the first set built a world of order, ritual, and false hope, Hour of Devastation tears it down. It is Magic's seventy-fifth expansion, and one of its more unambiguously grim ones.

What is Hour of Devastation?

Hour of Devastation (set code: HOU) is a small expansion released on July 14, 2017. It follows Amonkhet (AKH) as the second set in the Amonkhet block, completing the story arc that began there.

As a small set in a two-set block - the last era of that structure before Wizards moved to standalone sets - HOU is designed to be drafted alongside Amonkhet. Its 209 cards wrap up the mechanical and narrative threads AKH introduced, while pushing them toward catastrophe.

Lore and setting

The plane of Amonkhet was presented in the first set as a structured, if oppressive, society: an Egypt-inspired world ruled by five trials, a false god-pharaoh, and the distant promise of the Worthy Dead. Underneath that surface, the elder dragon Nicol Bolas had been pulling every string.

Hour of Devastation is the moment the strings snap.

The set takes its name from the Hours - a series of apocalyptic events that Bolas unleashes on Amonkhet to harvest an undead army. The sun goes wrong. The gods begin to fall. The society the inhabitants of Amonkhet had built their entire lives around collapses in front of them. It's a rare Magic set that commits this completely to a downer ending, and that willingness to follow through gives the cards a genuine emotional weight.

Several planeswalkers are present on Amonkhet during these events, and the set doesn't spare them from the consequences.

Themes and mechanics

Hour of Devastation builds on the mechanical foundations of Amonkhet while adding new tools that reflect the set's tone of escalating disaster.

Returning from Amonkhet

• Embalm returns - creatures that can be exiled from the graveyard to create a token copy, now as a white mummy. HOU expands on this with its new counterpart.
• -1/-1 counters remain a core mechanical thread, tying into black and green strategies.
• Exert returns as well, the mechanic where creatures can push harder at the cost of not untapping.

New in Hour of Devastation

• Eternalize is the set's signature new mechanic, a darker mirror of embalm. Where embalm creates a white token, eternalize creates a 4/4 black Zombie version of the creature - same name, abilities, no power or toughness from the original. It captures the set's theme perfectly: something familiar, transformed into something colder and more threatening.
• Afflict is a triggered ability that punishes opponents for blocking. When a creature with afflict is blocked, the defending player loses life equal to the afflict value. It rewards aggressive, go-wide strategies and makes combat decisions genuinely painful.

Limited and Draft

In Draft, HOU was typically opened alongside two packs of Amonkhet - a classic small-set draft structure. This meant the mechanics of both sets were in play simultaneously, which rewarded drafters who understood how embalm, eternalize, exert, and -1/-1 counters interact.

Afflict pushed the Limited format toward aggressive strategies. A creature that punishes the opponent whether they block or not creates a specific kind of tension on the board that's different from regular evasion - it's not that the creature can't be stopped, it's that stopping it costs something either way.

The -1/-1 counter synergies created interesting decisions around creatures that wanted to shed counters or benefit from having them. Green and black in particular had ways to make those counters work in your favour rather than simply weakening your board.

Notable cards and comparisons

As with any set, some cards in HOU are doing more work than others - and some are doing less work than their predecessors.

A few honest comparisons worth knowing:

• Ambuscade is strictly worse than Clear Shot.
• Carrion Screecher is strictly worse than Wake of Vultures.
• Frilled Sandwalla is strictly worse than Basking Rootwalla.
• Open Fire is strictly worse than Brimstone Volley, Lightning Bolt, Lightning Strike, Puncture Blast, Searing Spear, and Urza's Rage.

These comparisons matter most in formats where the older cards are available. In Standard at the time, Open Fire and Ambuscade were doing real work simply because their superior versions weren't legal - a good reminder that card quality is always format-relative.

Format check: HOU has rotated out of Standard. Check current format legality on Scryfall or the official Magic site before building.

Set legacy

Hour of Devastation is remembered for a few things that go beyond its card list.

Narratively, it marks one of Magic's more committed acts of genuine consequence in its story. Bolas doesn't just threaten - he wins, at least in the short term. The gods of Amonkhet are killed or corrupted. The people of the plane suffer real losses. It's a darker endpoint than most Magic sets allow themselves, and players who were following the story at the time felt it.

Mechanically, eternalize is a clean and flavourful design - the idea that death on Amonkhet doesn't mean rest, but transformation into something alien and powerful, lands well both in the story and at the table. Afflict, while more situational, added texture to aggressive strategies that pure evasion wouldn't have.

As the last small set before Wizards retired the two-set block structure, HOU also marks the end of an era in how Magic sets were organised. The move to standalone sets that followed changed how Limited formats worked, how sets told stories, and how mechanics were introduced. In that sense, Hour of Devastation is a closing chapter twice over - for Amonkhet's story, and for a particular way of making Magic sets.
