Key cards

The headline chase cards in Night Unison include:

Tag Team GX: Greninja & Zoroark-GX (Dark type) and Gardevoir & Sylveon-GX (Fairy type) headline the set as dual-Pokémon powerhouses. Both appear in RR, SR (Full Art), and HR (Hyper Rare / Rainbow) versions.

GX cards: Incineroar-GX and Cobalion-GX provide additional GX options. Each has RR and SR printings.

Secret Rares: The set contains UR (Ultra Rare) trainer cards beyond the main numbered portion. Notable trainers include Erika’s Hospitality and Pokémon Communication, both popular in competitive play.

What is in the box

A Japanese SM9a Night Unison booster box contains 30 packs, each with 5 cards. Every pack includes at least one holo or reverse-holo card. As a subset/enhancement pack, the box is smaller than a main expansion box. The pull rate for SR and HR cards is roughly one per box on average.
