The second Grand Rush set includes a large selection of Generation III Pokémon plus a number of high-grade Pokémon that continue to support the new Double Rush and Combo Rush mechanics. Grade 5 Legendary Pokémon Groudon and Kyogre could both be encountered on the flagship launch course, each of which has the ability perform Double Rush. Courses added to the play roster during the set's duration introduced more Grade 5 Legendary Pokémon able to perform Double Rush, including the Eon Pokémon Latias and Latios from early October, the Synthetic Pokémon Silvally from mid-October, Kalos Pokémon Xerneas and Yveltal from late October, and the Boundary Pokémon Kyurem from early November. Most standard courses began to feature an Ultra Beast Appears! icon on the course selection menu from October 17, 2019, indicating players could encounter Ultra BeastsNihilego and Xurkitree during play. Both appear as Grade 5 Pokémon with the Double Rush ability. Pokémon supporting the Combo Rush mechanic in this set include the final evolutions of the Generation III starter PokémonSceptile, Blaziken, and Marshtomp, and Legendary titansRegirock, Regice, and Registeel. Each Pokémon within these groups of three can Combo Rush with one another. EeveelutionsEspeon and Umbreon can also Combo Rush with each other, as can Meteorite Pokémon Lunatone and Solrock.
As part of a tie-in with the anime, a special Alola League Champion Course became available to play on September 16, 2019 following the first broadcast of Enter the Champion! a day earlier in Japan that saw Ash become a Pokémon League Champion for the first time. This course includes the five Pokémon used by Ash during the Manalo Conference, which are dispensed as Promotional disks if captured. When used in-game, Ash will appear on-screen just before one of these Pokémon attacks.
Promoting the upcoming Pokémon Sword and Shield games, a special roulette could randomly activate in place of the regular Attack Roulette starting October 17, 2019 for the remainder of the set's duration. The Pokémon Sword & Shield Roulette! (Japanese: ポケモン ソード・シールド ルーレット！) replaces all attack bonus values with differently-colored symbols bearing silhouettes of the Generation VIII starter Pokémon. Successfully selecting the green symbol will summon Grookey to attack with Razor Leaf; selecting the red symbol will summon Scorbunny to attack with Ember; selecting the blue symbol will summon Sobble to attack with Water Gun. If a Pokémon is summoned, it will attack before the player's chosen Pokémon uses its move.
Trainer and Battle Mode became available to play from October 24, 2019 and provided a new roster of opponents to battle. The lineup included two new Trainers classes and a new Battle Leader, Ibure, who could not be challenged until the other four Trainers had been defeated. Promotional Solgaleo or Lunala could be dispensed for an additional ¥100 following a battle with Ibure, with 'WINNER' versions available to those who successfully defeated his team. Solgaleo and Lunala are also able to Combo Rush with one another.
Pinsir and Heracross were added as Support Pokémon from this set. Players registering a Ga-Olé Pass for the first time would automatically receive Heracross as a Support Pokémon as part of the Pokémon Ga-Olé Welcome Campaign.
