Scars of Mirrodin contains 249 cards (101 Common, 60 Uncommon, 53 Rare, 15 Mythic, 20 Basic Lands), including randomly inserted premium versions of all cards in the set. The expansion symbol of the set is a corroding hexplate from the Glimmervoid.
Scars of Mirrodin returns to the plane of Mirrodin, previously the setting of the block and the set of the same name.   As Mirrodin is an artificial plane, the number of artifacts and cards relating to that permanent type is larger than in other sets and mechanically reflects the themes already explored in the previous sets. 
The set describes the conflict between two major factions - one being Mirrodin, and the other being the invading forces of Phyrexia. Cards aligned with these two factions are watermarked, as previously seen with the Guild aligned cards in Ravnica block. The two factions are also mechanically separated, with the Phyrexians dealing largely with Poison, Infect and Proliferate, as well as sacrifice or leaves play effects, while the native Mirrans use mechanics already introduced or similar to those of the original Mirrodin set - Imprint, Indestructible, Charge Counters the new Metalcraft mechanic, as well as Mana Myr and Spellbombs. Only 40 cards of the set have the Phyrexian symbol on them. All other cards except for Basic lands and Planeswalker cards have a Mirran watermark.
Flavor and storyline
|“||The corrosion begins||”|
The metal plane of Mirrodin shines under the light of five suns ... but it’s now tarnished by the deadly scourge known as Phyrexia. Besides the Mirran-Phyrexian conflict, the story also revolves around several planeswalkers. Elspeth Tirel (as a new card of the same name, Elspeth Tirel) returns while a new planeswalker by the name of Koth is introduced who appears to be of Vulshok heritage and thus would be native to Mirrodin. His card is called Koth of the Hammer, making his name an acronym of the name of the card. Venser and Tezzeret are also involved in the storyline, the former confirmed to getting a new card, Venser, the Sojourner.
Being set on Mirrodin, the expansion features themes and settings already known from that plane. For example, creature types and tribes of these such as Leonin (Cats), Vampires, Loxodon (Elephants), Elves , or the Human tribes of Vulshok, Sylvok, Auriok, Moriok and Neurok. Artifact creatures such as Golems and Myr also return.

Infect is a new keyword that causes creatures to deal damage to other creatures in the form of -1/-1 counters, similar to Wither. However, in addition to this, cards with Infect deal damage to players in the form of poison counters. The poison mechanic was introduced in Legends but has never been strongly supported. The mechanic resurfaced in Time Spiral block with a reprint of Swamp Mosquito and the Poisonous keyword (which does not appear in Scars of Mirrodin).  Poison counters would be a major theme of the entire block.
A new keyword action in Proliferate works in combination with Infect.  When a player proliferates, he or she chooses any number of permanents and/or players with counters on them, and puts another counter of a kind it has on it. E.g. a player proliferates and chooses an opponent with a poison counter, a creature with a -1/-1 counter, a Planeswalker with loyalty counters and an artifact with a charge counter. Everyone of these entities gets another of these respective counters.
The ability word Metalcraft gives a card a bonus if its controller controls three or more artifacts.  Scars of Mirrodin features a new Mox named Mox Opal that has Metalcraft. The Indestructible mechanic returns with new "Darksteel"-themed cards, as does the Imprint mechanic from Mirrodin.
The only returning keyword from the original Mirrodin block was imprint, this keyword allows a player to "imprint" some card on the artifact (removing that card from the game). That artifact's effect depends on the card imprinted (for example you can imprint a creature on Semblance Anvil to reduce costs of spells that share a card type with that card).
Scars of Mirrodin has 8 Cycles:
- Mana Myr: Each of these common myr artifact creatures costs and has a mana ability in which they tap, and which produce a color-appropriate mana. Each represents a zone of Mirrodin corresponding to the color. Each is illustrated by Alan Pollack. Reprinted from Mirrodin. — Gold Myr, Silver Myr, Leaden Myr, Iron Myr, and Copper Myr 
- Smiths: Each of these creatures is a human artificer and creates an effect when their controllers cast an artifact spell. — Myrsmith, Riddlesmith, Painsmith, Embersmith, and Lifesmith
- Replicas: Artifact creatures that can be sacrificed after paying a form of colored mana to get a color-specific effect. — Auriok Replica, Neurok Replica, Moriok Replica, Vulshok Replica, Sylvok Replica
- Color-aligned Artifact creatures: A cycle of creatures who have a colorless cost, but an activated ability including one mana of one of the five colors. The white card breaks the cycle a little, since it is not permanently an artifact creature. — Glint Hawk Idol, Soliton, Vector Asp, Saberclaw Golem, Wall of Tanglecord
- Spellbombs: Artifacts that can be tapped and sacrificed to create an effect. Its owner can pay one mana of a specific color to draw a card when these artifacts are put in the graveyard: Origin Spellbomb, Flight Spellbomb, Nihil Spellbomb, Panic Spellbomb, Horizon Spellbomb

- Taplands: A new set of allied-colored Taplands was introduced, with the twist that these could come into play untapped if they are played during the first few turns of the game.  — Seachrome Coast, Darkslick Shores, Blackcleave Cliffs, Copperline Gorge, Razorverge Thicket.
- Vanilla creatures: There is 1 vanilla common creature of each color. Loxodon Wayfarer, Plated Seastrider, Moriok Reaver, Scoria Elemental, Alpha Tyrranax

- Golem's Heart is functionally similar to the Darksteel Lucky charms but was strangely enough created/predicted in its entirety, including name, by MTGSalvation user luminum_can.
- Molten-Tail Masticore is a near-functional reprint of the original Masticore, sharing casting cost, power/toughness, type and two if its abilities. However, since Masticore is on the Reserved List, it could not be reprinted and the damage ability was replaced by another damage ability.
- Mox Opal - yet another installment of the famous Moxen (zero-mana artifacts producing all colors of mana).
- Prototype Portal is functionally very similar to the Mirrodin card Soul Foundry, but replaces creatures with artifacts. This makes Prototype Portal the second card to specifically produce non-creature Tokens after Imperial Mask from Future Sight.
- Tower of Calamities completes a cycle started in Mirrodin which had four cards with the word Tower in their name. All of them cost and have an activated ability for the cost of , generating a usually color-aligned effect. The respective colors are also used heavily in the artwork. They are Tower of Champions (green), Tower of Eons (white), Tower of Fortunes (blue) and Tower of Murmurs (black). Tower of Calamities adds a red-aligned effect.
- Venser, the Sojourner is the only multicolored card in the set. It also marks the return of Venser after his original appearance (pre-ascension), as Venser, Shaper Savant in Future Sight.
