Yu-Gi-Oh! Maze of Machines Reportedly Reveals Rampant Barrel Dragon, March 19, 2027
Maze of Machines reportedly brings DARK Machine support, 10 GX cards, chibi Secret Rares and a 153-card list, with a March 19th, 2027 sale date.

Maze of Machines, the Yu-Gi-Oh! TCG set reportedly going on sale March 19th, 2027, has reportedly had its DARK Machine core revealed, led by MZMC-005 Rampant Barrel Dragon, a Level 8 Fusion with 3000 ATK. None of this is confirmed yet.
Maze of Machines Rampant Barrel Dragon and DARK Machine Cards
Rampant Barrel Dragon is a Quick Effect coin-flip boss. It flips 3 coins and applies an effect for each head, with no drawbacks or costs.
- Alpha Barrel lets you add any card to your hand.
- Beta Barrel: destroys an opponent's card for each head.
- Omega Barrel takes a card out of the opponent's Graveyard and puts it on your side of the field.
TCGKing's take: three free coin flips with no cost is a bold design, so wait for the final text before judging it.
MZMC-001, MZMC-002 and MZMC-003 Support Cards
MZMC-001 Pendulum Machine of Misery (Level 6, ATK 1750, DEF 2000) can be Special Summoned from your hand whenever a DARK Machine destroys a card. Upon being summoned it destroys one of the opponent's monsters, and should it be destroyed itself, it brings out a DARK Machine from the Deck.
MZMC-002 Slot Machine 777 (Level 7, ATK 2000, DEF 2300) resists destruction by attacks in Attack Position and by effects in Defense Position. During your turn it searches a "Heavy Metal" Spell from the Deck, and every time it does so it permanently gains 700 ATK or DEF.
MZMC-003 Ticking Blast Sphere (Level 6, ATK 2900, DEF 1400) equips to an effect monster each time it is Special Summoned. It destroys that monster when a monster effect is next activated, then burns the opponent for its original ATK. When it is destroyed, a "Heavy Metal" Trap is Set from the Deck.
Heavy Metal Spells and Traps
- MZMC-010 Heavy Metal Revenge is a Continuous Trap that brings back a monster from either Graveyard under your control, provided a DARK Machine monster's effect destroyed it.
- MZMC-006 Heavy Metal Bandit is a Continuous Spell that protects DARK Machines from opponent's Spells and searches a DARK Machine with 2000+ ATK or DEF.
- MZMC-009 is a "Heavy Metalmorph" Trap. It references a future, still unrevealed "Barrel Dragon" prototype meant to work together with MZMC-001 and MZMC-002.
