S2a: Explosive Walker is a Japanese Pokémon TCG expansion from the Sword & Shield era, released on April 24, 2020 and sitting between S2: Rebellion Crash and S3: Infinity Zone. The set code is S2a, and the card list runs to 86 catalog printings. Its identity comes through repeated names rather than a single headline Pokémon: Kabu and Pokemon Breeder's Nurturing each appear in three versions, while Big Parasol, Butterfree V and Butterfree VMAX each appear twice. Trainer cards sit at the top of the value list alongside Vikavolt V and Gardevoir V.

The Explosive Walker card list builds from Common and Uncommon up through Rare to a chase tier of 25 cards across Super Rare, Double Rare, Triple Rare, Ultra Rare and Hyper Rare. The most valuable cards are the Hyper Rare Pokemon Breeder's Nurturing, the Super Rare Vikavolt V, the Super Rare Pokemon Breeder's Nurturing, the Super Rare Gardevoir V and the Hyper Rare Centiskorch VMAX. The top five cards hold 35 percent of the set's total card value, a fairly even spread, so the chase cards here are not dominated by a single pull.

Completing S2a: Explosive Walker means tracking down all 86 catalog printings, 77 of which currently carry a price. With the top five cards holding only 35 percent of total value, the cost of a complete set is spread across the chase tier instead of resting on a few pulls. The sealed line is small, made up of a booster box and a booster pack, so most collectors working on the set will be buying singles for the Super Rare, Triple Rare and Hyper Rare cards.
