Shadows over Innistrad Remastered (SIR) Set Guide

Some of Magic's most beloved horror-gothic storytelling returned to Magic: The Gathering Arena on March 21, 2023, when Shadows over Innistrad Remastered (SIR) brought 294 cards from the Shadows over Innistrad era back into the digital spotlight. If you never got to draft the original sets - or you just want another pass through werewolves, vampires, and creeping cosmic dread - SIR was the set that made it possible.

What is Shadows over Innistrad Remastered?

Shadows over Innistrad Remastered is a Magic: The Gathering Arena-exclusive reprint set released on March 21, 2023. It carries the set code SIR and contains 294 cards. Like other remastered sets on Arena - think Amonkhet Remastered or Kaladesh Remastered - it doesn't represent a brand-new set of original cards. Instead, it's a curated collection pulling from the original Shadows over Innistrad (SOI, 2016) and Eldritch Moon (EMN, 2016), the two sets that formed the Shadows over Innistrad block.

Because SIR is an Arena-specific release, it has no physical paper version. The cards it adds to Arena are legal in the Historic format, giving players access to powerful Innistrad-block cards that weren't previously available on the platform.

Format check: SIR cards are Historic-legal on Magic: The Gathering Arena. They are not legal in Standard, Pioneer, or any paper-only format by virtue of this release alone - paper legality depends on whether a card has been printed in a format-legal set.

The Shadows of the Past bonus sheet

Alongside the main 294-card set, SIR comes with a companion bonus sheet called Shadows of the Past. Bonus sheets have become a beloved part of remastered sets on Arena - they're a curated selection of cards that can appear in packs as an extra, often pulling from a wider range of Magic history than the main set itself.

Shadows of the Past is its own Historic-legal set of cards, associated with SIR but treated separately. Several of the cards on the bonus sheet were already present on Arena before SIR launched through earlier releases like Historic Anthology, Jumpstart, Jumpstart: Historic Horizons, and the Mystical Archive. Cards like Avacyn, Angel of Hope, Faithless Looting, Unburial Rites, and Spider Spawning had prior Arena homes - the bonus sheet gave them a new way to show up in SIR packs.

One card worth noting for collectors: Immerwolf received brand-new artwork specifically for the Shadows of the Past bonus sheet, making SIR its first home for that new illustration.

Themes and mechanics

Because SIR draws directly from the Shadows over Innistrad block, it brings back the mechanical identity of that era wholesale. Innistrad has always been Magic's horror plane, and the SOI block leaned hard into Gothic atmosphere - the mechanics reflect it.

The Shadows over Innistrad block introduced and featured several memorable mechanics:

• Transform - double-faced cards that flip between two states, most famously the werewolf creatures that transform between human and beast forms based on how many spells players cast in a turn.
• Investigate - creating Clue artifact tokens that can be sacrificed to draw cards, representing the mystery-solving narrative threaded through the original story.
• Delirium - a keyword condition rewarding players for having four or more card types in their graveyard, pushing graveyard-filling strategies.
• Skulk - a keyword ability that prevents creatures with skulk from being blocked by creatures with greater power.
• Emerge - from Eldritch Moon, letting players cast large Eldrazi creatures by sacrificing another creature and paying a reduced cost.
• Escalate - also from EMN, a modal spell mechanic where players can pay additional costs to choose more modes.
• Meld - one of Magic's most dramatic mechanics, where two specific cards combine into a single oversized card when both are on the battlefield simultaneously.

The set's mechanical identity as a whole is built around the graveyard, transformation, and the tension between holding resources and spending them - fitting for a story about a world tipping slowly into darkness.

Lore and setting

Innistrad is Magic's Gothic horror plane: a world of perpetual twilight, ancient churches, dark forests, and monster-haunted villages. The Shadows over Innistrad story is one of the game's most celebrated narrative arcs.

In the original block's story, the archangel Avacyn - protector of humanity on Innistrad - has gone inexplicably mad, and the protective wards that kept monsters at bay are failing. Planeswalker Jace Beleren and vampire aristocrat Sorin Markov investigate the growing darkness, eventually uncovering that the Eldrazi titan Emrakul has been subtly manipulating events from afar, driving both humans and monsters to madness. By Eldritch Moon, Innistrad is overrun with Eldrazi corruption, and it takes the combined effort of multiple Planeswalkers to trap Emrakul - sealed inside the plane's silver moon itself.

It's a rare story where the heroes win, but at tremendous cost, and the shadow of what happened lingers over Innistrad's subsequent appearances. If you haven't read the original story, the card art and flavor text in SIR do a remarkable job of telling it in fragments.

Notable cards and the Shadows of the Past sheet

The source material for SIR doesn't call out specific format staples from the main 294-card set by name, so I won't speculate about individual card power levels - the Historic meta shifts often enough that any snapshot would date quickly.

What I can highlight is the Shadows of the Past bonus sheet, which notably includes cards that carry real Historic weight:

• Faithless Looting - previously introduced to Arena via the Mystical Archive (Strixhaven: School of Mages, 2021), this card has a long history of enabling graveyard and reanimator strategies across formats.
• Avacyn, Angel of Hope - a powerful finisher with a history of Commander and casual appeal, previously on Arena via Historic Anthology.
• Unburial Rites and Spider Spawning - graveyard-centric cards that fit naturally with SIR's delirium and graveyard themes.

One technical note worth flagging: a bug was discovered related to Gutter Grime and changes made to how self-referencing cards work. This bug caused Ninja's Kunai and Citizen's Crowbar to incorrectly sacrifice all permanents controlled by the ability's controller. It's an interesting reminder of how interconnected Arena's rules engine can be - a change to one card's self-reference logic rippled unexpectedly into unrelated cards.

Set legacy

Shadows over Innistrad Remastered sits in an interesting position. The original SOI block is remembered fondly as one of the strongest draft formats of the mid-2010s, and as a narrative high point for Magic's storytelling. The remastered version gave Arena players - many of whom came to the game years after 2016 - a first chance to experience that draft environment digitally.

For the Historic format, SIR expanded the card pool meaningfully, adding graveyard tools and transform mechanics that opened new deckbuilding space. The Shadows of the Past bonus sheet, even with some overlap from earlier Arena releases, consolidated a range of useful cards into one accessible place.

It's also part of a broader pattern of Arena remastered sets honoring Magic's history on a platform that couldn't otherwise access older cards - a way of making thirty years of Magic feel alive and playable rather than locked in the past.
