Yu-Gi-Oh! TCGMaze of the Master contains plenty of quarter century secret rare and collector’s rare cards to liven up your binder. From additional Tachyon cards to updating the selection of Odion-centric cards, there are plenty of interesting cards to use as upgrades for existing decks or to start a new build entirely.
Of course, with each set in Yu-Gi-Oh! there is always the question as to which cards are the most valuable. For some fans, this gives you a better idea of whether a pull is good for your collection or if it’s one that can serve as a decent rarity bump to take to a competition.

10Treasures Of The Kings - Collector’s Rare - $33.29
The Treasured Field Spell
Field Spells always go for something if they’re good. As a collector’s rare, this card has a bit more flair added to it with a special card texture. If you plan to play the Odion support, then this is one of the necessary cards to make it work.
It lets you set your Apophis Traps from the deck while also searching for other Temple of the Kings cards if you meet the conditions. This means having either two other set cards on the field orhaving a Trap in the graveyard. Luckily, this requirement is quite generic.

9Merciless Scorpion Of Serket - Collector’s Rare - $34.94
A Fearsome Retrain
The good thing about all the Temple of the Kings cards is that they can search each other out.This one lets you search out a Spellthat mentions Temple of the Kings. Being a collector’s rare isn’t the only special thing about this card, though.
Merciless Scorpion of Serket is a retrain of a classic card, Mystical Beast of Serket. However, this time around, it gets a stronger attack buff effect, more synergy within an archetype, and a way to Special Summon itself out without tributing.

8X-Cross Cannon - Collector’s Rare - $39.62
Assemble The XYZs
The XYZ Dragon archetype is known for being able to assemble itself into a much larger Fusion Monster. Maze of the Master contains updates for this archetype in the form of different monsters and retrains. X-Cross Cannon is one of these updates.
It can equip itself with another Light Machine Union monster straight from the deck. It also has a unique wording that makes the equip count as if the chosen card’s own effect did it. It is also the only piece in the set that gets a collector’s rare printing.

7Trickstar Aqua Angel - Collector’s Rare - $49.72
Look At Your Opponent’s Hand And Field
Trickstar Aqua Angel has an effect that lets you predict all of your opponent’s plays. If youuse it as Link material, you’re able to look at your opponent’s hand and the face-down cards they control. This includes face-down monsters, Traps, and Spells.
Interestingly enough, this card also lets you Special Summon it from your hand or graveyard as long as you have another Trickstar or Marincess monster on your side of the field. This makes it easier to get it out and Link it for the battle protection it offers.

6Atlantean Heavy Infantry - Collector’s Rare - $52.76
Rarity Bump Your Atlantean Deck
Getting a copy of Atlantean Heavy Infantry could be quite expensive due to it only being printed twice before Maze of the Master. Luckily, this set includes it in the abundant rare style. However, if you love to rarity bump your cards to the top, you can find it as a collector’s rare.
This card gets you an extra Normal Summon during your Main Phase. If you use it as part of the cost to activate a Water monster’s effect, you also get to pop a card on the field. So it acts as both an extender and a way to start picking at your opponent’s board.

5Mulcharmy Purulia - Collector’s Rare - $54.23
One Reprinted Mulcharmy
Mulcharmy Purulia gets a collector’s rare printing in Maze of the Master. The Mulcharmy cards give players plenty of advantages by allowing you to draw multiple cards while your opponent performs their plays for the turn.
Each time they Normal or Special Summon from the hand, you get to draw a card. The Mulcharmy cards are essentially Maxx C if it were split into three different monsters. While not as sparkly asthe quarter-century secret rare version, it’s nice to see it get different rarities and reprints.

4Number 107: Galaxy-Eyes Tachyon Dragon - Quarter Century Secret Rare - $65.36
Quarter Century Printing With An Alternate Art
Getting a copy of Number 107: Galaxy-Eyes Tachyon Dragon is fairly easy in Maze of the Master. What makes this copy so special is that it is a quarter-century secret rare and has an alternate art only found in this rarity.
That means if you want to get it with the alternate art, this is the only option. Of course, Number 107: Galaxy-Eyes Tachyon Dragon has some good effects as well. It can beef itself up, swing multiple times, and even blanket negate everything during the Battle Phase.

3Seventh Tachyon - Secret Rare - $66.30
Matching Traits To Search Cards
Seventh Tachyon is the card everyone wants from Maze of the Master. This generic searcher even makes the secret rare version a highly coveted card. All you need is an XYZ Number monster in your extra deck to call out between 101 and 107.
Then it’s just a game of matching attributes, ranks, and levels together to see what you can search out. Interestingly enough, Maze of the Master adds secret rares to the set, so you aren’t just hunting out for ultra rare cards.

2Silent Magician LV8 - Quarter Century Secret Rare - $83.34
One Of Yugi’s Main Monsters
Silent Magician LV8 is a card from when Yu-Gi-Oh! experimented with monsters that could level up each turn. One of these cards was Silent Magician, which was used by Yugi in the anime to differentiate himself from Atem.
Maze of the Master gives Silent Magician LV8 an exclusive alternate art that is only available as a quarter-century secret rare. While not a great card competitively, this is a great nod to the Duel Monsters era in a series of sets that revolve mostly around the anime.

1Seventh Tachyon - Collector’s Rare - $118.00
The Ultimate Version Of The Chase Card
Seventh Tachyon also has a collector’s rare, which is the chase card for the set. This is the highest rarity you can find this card in, and seeing as it is already one of the best cards to play, getting a collector’s rare makes sense.
This is the ultimate flex when you need to search for something from the deck. Just ensure you have those Number monsters in the extra deck on standby. Use it in a Tachyon deck or use it as a generic searcher by sliding in a valid monster.
