Starter decks have their own set identifier (ST-01, ST-02, etc.) separate from booster sets (OP-01, OP-02, etc.)

TCG is known for bringing back many iconic cards and packs that were released in the past to make some of their products more accessible

Arceus and the Jewel of Life Zoroark - Master of Illusions Black: Victini & ReshiramWhite: Victini & Zekrom Kyurem VS The Sword of Justice -Meloetta's Midnight Serenade Genesect and the Legend Awakened Diancie & The Cocoon of Destruction Hoopa & The Clash of Ages Volcanion and the Mechanical Marvel Pokmon I Choose You

These vendors take the card and collectible hobby very seriously

One of the reasons I like CGC is the quick turnaround so that is less of an issue here
