This Japanese-language Alolan Muk-GX comes from the 2017 Sun & Moon “To Have Seen the Battle Rainbow” expansion (SM3H). The card features vivid foil art by 5ban Graphics, with Alolan Muk spewing neon-green and purple sludge against a swirling rainbow-holo background that captures the set’s colorful theme. As a GX trading card with 220 HP and a powerful Poison-type GX attack, it’s appealing for play, and collectors prize its Japan-only artwork and double-rare (RR) foil rarity. This striking Pokemon TCG card combines strong in-game stats with eye-catching design, making it a standout addition to any Alolan Muk or GX card collection.
