Rainbow Edition Series 2 leans all the way into color. Each booster box holds 20 packs of 5 cards (100 cards total) plus an exclusive Overseas Limited PR card, “Fly to the Moon!,” showing Twilight Sparkle, Fluttershy, and Rainbow Dash drifting through a starry night sky. The standout subset is the XR tier: eight warm, autumn-picnic scene illustrations starring Twilight Sparkle, Pinkie Pie, Rainbow Dash, Rarity, Fluttershy, and Applejack, capped by a full group artwork card. Layer in a refreshed art style on the USR tier and a new run of outfit-change cards, and Rainbow Edition Series 2 reads as the most purely “fun unboxing” set of the three — less about a single chase grail, more about the sheer density of vibrant, foil-heavy artwork packed into one box.
