ONSLAUGHT

Onslaught is a Magic: The Gathering standard-legal expansion released on 7 October 2002 (24 years ago) with 350 cards in the set, using the set code ONS. A standard-legal expansion - the main type of Magic release, with its own world, mechanics and draft environment. On this page you can browse every Onslaught product we track - booster packs, booster boxes and preconstructed decks - and jump straight into the full Onslaught card list with daily updated prices.

Opening Onslaught boosters and booster boxes

A sealed Onslaught booster box is the cheapest way to open ONS cards in bulk, while collector boosters concentrate the foil and extended-art treatments. Compare the sealed prices above before you buy: box prices move with the value of the set's rares, so a set with expensive mythics usually has expensive boxes too.

Onslaught card prices and how we track them

Every ONS single on Magicmark.io carries a market price in EUR and USD, a price trend, and 1-day, 7-day and 30-day averages, rebuilt daily from Cardmarket "from" prices plus other marketplaces. That means the Onslaught price you see is what a near-mint copy actually sells for today, not the value it had at release in 2002. Foils, etched foils and special treatments are priced separately, so you never compare a non-foil ONS rare to its foil version by accident.
