Onslaught, like its following expansions in the Onslaught block, Legions and Scourge, featured a theme that focused heavily on "tribal" cards, or cards that are concerned with creature types.   The set contains 350 black-bordered cards (110 rare, 110 uncommon, 110 common, and 20 basic lands). Onslaught's expansion symbol is a stylized morphed creature. 
Onslaught was sold in 75-card tournament decks, 15-card boosters, four preconstructed theme decks and a fat pack.  For the first time, there were four different booster packs. They featured artwork from Jareth, Leonine Titan, Kamahl, Fist of Krosa, Blistering Firecat and Grinning Demon. The prerelease card was a foil Silent Specter.  The set was accompanied by the novel of the same name.
Flavor and storyline
A continuation of the storyline developed in the Odyssey Cycle, Onslaught and the Onslaught Cycle are set on the continent of Otaria on the devastated plane of Dominaria, approximately a century after the events of Apocalypse of the Invasion block.   Kamahl has relocated to the Krosan Forest with the Mirari and becomes a druid of Krosa. The power of the Mirari begins to work on the forest, mutating its residents and growing some of them to gigantic proportions. Meanwhile, Kamahl's sister Jeska is transformed by foul Cabal healing magic, into Phage, a pit fighter whose touch brings death. The illusionist Ixidor discovers his new powers of reality sculpting. Ixidor uses his new power to create the angel Akroma.

Themes and mechanics
Tribal and creature types were a prominent theme in the Onslaught block. Some creature types bled into colors other than their normal colors (e.g., Festering Goblin, a black, non-red Goblin), for more design space and variety.
|Creature subtype||Tribe name||Primary color||Secondary color(s)|
|Beast|| Red ()
| Blue ()|
|Birds|| Aven (in white and blue only)
| White ()
| Black ()|
|Clerics|| White ()
|Dragons||Red ()||Blue ()|
|Goblins||Red ()||Black ()|
|Illusions||Mistform (or Mimics)[note 1]||Blue ()|
|Soldiers||White ()|| Blue ()|
|Wizards||Blue ()||All other colors ()|
Numerous cards with class creature types, as opposed to species or race ones, such as the Cleric, Soldier, and Wizards creature types, were retroactively given additional (species or race) creature types during the Grand Creature Type Update to be more consistent with the "race-class model". In most of these cases, the additional creature type was Human. This, by and large, did not cause significant changes to this expansion or block. In 2002, a poll conducted on MTG.com showed that a majority of respondents were opposed to the idea of Human as a creature type.
Dragons have a small presence in Onslaught, with the only Dragon creature cards being Quicksilver Dragon and Rorix Bladewing (and an additional one enchantment dragon-creature-token-creating card in Dragon Roost). Dragons would go on to form a theme in Scourge, the third Onslaught block expansion.
Onslaught reintroduced the static keyword ability cycling and featured a number of mechanics, some of which were novel, including: 
- Fear: a keyword static ability of an established ability, fear, named after Fear, the Limited Edition aura card, and first card, that conferred or featured this ability, means "This creature can't be blocked except by artifact creatures and/or black creatures.".
- Gustcloak: a non-keyword triggered ability that allows the controller of a blocked creature with the ability to remove the creature from combat, thereby preventing all combat damage that would be dealt to and by it, similar to the effect of Maze of Ith.
- Lords: any card with an activated ability whose cost includes the tapping of a creature that shares a creature type with the lord (i.e., Ancestor's Prophet, Aphetto Grifter, Birchlore Rangers, Catapult Master, Catapult Squad, Crookclaw Elder, Gravespawn Sovereign, Shieldmage Elder, Skirk Fire Marshal, Spurred Wolverine, Supreme Inquisitor, Voice of the Woods, and Legions' Keeper of the Nine Gales). Cards somewhat similar to lords are Cryptic Gateway and Gangrenous Goliath, which, although they forward the tribal theme, do not tap creatures that share a creature subtype with the card itself.
- Morph: a static ability that allows the controller of a card with the morph ability to cast the card face-down as a 2/2 creature with no text, no name, no subtypes, no expansion symbol, and no mana cost.  
- Saboteurs: any creature card with a "Whenever this creature deals combat damage to a player" triggered ability.
- Self-recruiters: any card with an enters-the-battlefield triggered ability that allows its controller to search for a similarly named card, reveal that card, and put it into his or her hand.
- Cycling: originally conceived during Tempest design as "sliding" and first featured in Urza's Saga, was brought back from abeyance for reasons including "nostalgia", "exposing new[er] players [to older mechanics]", "[exploring] new twists [to the old mechanic]", "interaction with other mechanics", and "conservation of design space". To expand on cycling, a number of cards with cycling triggers,
The creature types Anteater (retroactively) and Mutant were introduced in Onslaught.
The following creature types that are not new to Magic are used in this expansion:
- Boar (retroactively)
- Fish (retroactively)
- Frog (retroactively)
- Goat (retroactively)
- Human (retroactively)
- Shaman (retroactively)
- Warrior (retroactively)
- Wolverine (retroactively)
The creature type Lord was used in this expansion at the time of printing but was later removed.
Onslaught features 13 cycles.
