Playing style

All "Mecha Phantom Beast" Main Deck monsters (excluding their Tuners and "Mecha Phantom Beast Kalgriffin") has the ability to gain the Levels of all Mecha Phantom Beast Tokens that the controller has, while every monster in the Archetype (excluding their Synchro Monsters) cannot be destroyed so long as a Token is on the field. In addition, most of their monsters are capable of generating the Deck's signature Tokens when certain conditions are fulfilled. Due to their Level modulation effect, this archetype can bring out a variety of Xyz Monsters, in particular Ranks 3, 4, 6, 7, 9 and 10, making them one of the most flexible Xyz-based archetype in the game, allowing them to Summon normally difficult Xyz Monsters such as "Number 92: Heart-eartH Dragon" with relative ease. As such, the Deck's strategy is a mixture of swarm and Xyz Summoning.

"Mecha Phantom Beasts" also have enormous potential in terms of Synchro Summoning with its own Tuners of choice: "Mecha Phantom Beast Warbluran", "Mecha Phantom Beast Blue Impala", and "Mecha Phantom Beast O-Lion". "O-Lion" is the ones commonly used, since it can facilitate additional Normal Summon once it's in the Graveyard, in addition to its Token-generating effect, increasing the deck's overall speed (especially with "Mathematician" and "Foolish Burial"), while "Blue Impala" is a little more restrictive and is mostly used to Synchro Summon "Concoruda" or in "Karakuri" hybrid decks. "Mecha Phantom Beast Warbluran" is less commonly used, but it offers better choices for Synchro Summoning than "O-Lion", allowing players to expand their Synchro Summoning options.

Despite they are being an Xyz-oriented archetype, their Main Deck monsters can also survive on their own due to their wide range of effects. "Mecha Phantom Beast Tetherwolf" and "Mecha Phantom Beast Blackfalcon" dominating battles, while "Mecha Phantom Beast Stealthray" and "Mecha Phantom Beast Coltwing" can destroy troublesome cards, all of which are easily accessible thanks to "Mecha Phantom Beast Megaraptor". As the result, the deck isn't entirely dependent on its Extra Deck arsenals, depending on how players may choose to build them.

Deck variants


This type is considered the most balanced among the Mecha Phantom Beast builds, it works by constantly generating Mecha Phantom Beast Tokens and utilizing them through various Mecha Phantom Beast monsters. "Scramble!! Scramble!!" is sometimes included, mostly used in conjunction with "Mecha Phantom Beast Coltwing" to generate more field presence, increasing the deck's speed significantly and quickly turn the tides, while "Mecha Phantom Beast Hamstrat", "Aerial Recharge", or sometimes "Vertical Landing" can provide the necessary setup for this card's activation. This deck can also utilizes various Synchro Monsters thanks to "Mecha Phantom Beast Warbluran" and "Mecha Phantom Beast O-Lion". O-Lion's extra Normal Summon ability also allows this deck to take faster approach with interaction of cards like "Mecha Phantom Beast Megaraptor" and "Mecha Phantom Beast Tetherwolf".

Due to their flexibility and constant Token generation, many high-Leveled monsters can be used, such as the "Monarchs", "Light and Darkness Dragon", or even 3-Tributers such as "Obelisk The Tormentor" or "Destiny HERO - Plasma". Due to Tokens are also treated as Normal Monsters, you can even include "Fusion Substitute" or "Performapal Trump Witch" to unleash "First of the Dragons".

Mecha Karakuri

The hybrid between Mecha Phantom Beast and "Karakuri", it utilizes "Mecha Phantom Beast Blue Impala" along with "Karakuri Watchdog mdl 313 "Saizan"" as their main Tuner to unleash multiple "Karakuri Shogun mdl 00 "Burei"s" at once in order to perform OTK similar to the original "Karakuri" decks.

Mecha Phantom HEROes

This variant utilize the synergy between "Mecha Phantom Beast" monsters along with "Masked HERO Divine Wind", which can be easily accessed thanks to "Mask Change II". Despite the heavy cost associated with the card, its aggressive-oriented property (being a Quick-Play Spell) combined with effects of "Divine Wind" and the fact that you can use Token as targets proves valuable for the theme as a whole, increasing the deck's speed and offensive power. "Mecha Phantom Beast O-Lion", in particular, is very effective to use as discard fodder for "Mask Change II" since it is searchable by "Mecha Phantom Beast Megaraptor", and also enables its extra Normal Summon and Token-generating effect to compensate.

To increase the effectiveness of "Mask Change II", "Strike of the Monarchs" can also be included as universal negation power, which can be used naturally in the deck due to "Mecha Phantom Beast" monsters' tendency of increasing their Level above Level 5 and most of them relies on Normal Summon (with or without O-Lion). Its other effect is an Attribute-modulation effect, which allows access to other "Masked HERO" monsters, such as "Masked HERO Dark Law", "Masked HERO Anki", or "Masked HERO Acid".

Hi-Speed Mecha Phantom Beast

Made possible with High-Speed Riders, this variant combines Mecha Phantom Beast with the components of "Speedroid" archetype. Unlike normal builds, this variant places more emphasis towards Synchro Summoning, utilizing the deck's Token generating ability along with "Speedroid Terrortop", "Speedroid Taketomborg", "Speedroid Double Yoyo", "Speed Recovery", and "Iron Call" in order to swarm the field easily. Taketomborg's ability also opens up access to "Speedroid Red-Eyed Dice" and "Speedroid Tri-Eyed Dice", giving the deck wide variety of Synchro Monsters available (especially with O-Lion included in the mix).

The advantage of this build over the other variants is aside from the aforementioned ones, is that the deck can utilize the best of "Transmodify", which can be used to access both "Terrortop" (with O-Lion) and "Megaraptor" (with Hamstrat, Terrortop, Taketomborg, or Tri-Eyed Dice), increasing the deck's consistency. Furthermore, the deck also able to access more powerful Synchro and Xyz Monsters that's difficult to Summon otherwise, such as "Clear Wing Synchro Dragon", "Mist Wurm", "Trishula, Dragon of the Ice Barrier" or even "Phantom Fortress Enterblathnir" (can be Summoned through "Cloudcastle"). The deck can also hit harder and faster than before (in terms of damage) thanks to "Hi-Speedroid Kendama" and "Hi-Speedroid Chanbara".

Recommended cards

Mecha Phantom Beasts


All "Mecha Phantom Beast" monsters are Machine-Type, so they share the weaknesses of "Acid Rain", "System Down", "Chimeratech Fortress Dragon", "Electric Virus", etc. "Chimeratech Fortress Dragon" can be used to easily eliminate your monsters, but fortunately can't send Tokens for its Summon. "System Down" is the most dangerous, since it can completely bypasses the anti-destruction effects of "Mecha Phantom Beast" monsters.

Also, since their built-in protection effect only covers destruction, cards that either banish, shuffle to the Deck, or negate their effects such as "Caius the Shadow Monarch", "Castel, the Skyblaster Musketeer", "Virgil, Rock Star of the Burning Abyss", "Nekroz of Unicore", "Breakthrough Skill", etc., can be a major threat.

"Bujin" Decks also pose a serious threat to this Deck, since their "Bujintei Susanowo" can easily destroy all monsters you control in a single Battle Phase. They're also capable of utilizing anti-Special Summon cards such as "Vanity's Emptiness", "Summon Limit", and "Kaiser Colosseum", since their Deck does not heavily rely on Special Summons. "Bujingi Turtle" and "Bujingi Hare" can also thwart any common removal attempt, since many offensive "Mecha Phantom Beast" effects rely on targeting and destroying.

In order to function properly, this Deck needs to constantly generate tokens. Because of this, cards such as "Poisonous Winds", "Power Filter", "Summon Limit", "El Shaddoll Winda", etc. can stall this Deck. Spell/Trap Card removal cards are essential for combating these kinds of threats.

Despite the deck's able to swarm the field quickly with both monsters and tokens, it is also their greatest weakness: Without tokens, most of their monsters are useless on their own, and even with tokens present, it's hard to utilize them without the matching "Mecha Phantom Beast" monster. This task has even more difficult due to the deck's over-reliance on "Megaraptor" to both getting the right monster along with accumulating resources, while "Megaraptor" itself is unsearchable through conventional means and needs Token Summoning assistance for triggering its effect in the first place, severely hampering the deck's overall speed in the long run.

Decks that use "Scramble!! Scramble!!" especially suffers the most from this limitation; without a way to setup the field with "Mecha Phantom Beast Tokens" (other than "Aerial Recharge", due to its maintenance cost), it is difficult to utilize it efficiently, especially if the monsters you supposed to Summon with it (usually "Harrliard" and/or "Coltwing") ended up in your hand, rendering "Scramble!! Scramble!!" itself unusable. It's also opens more vulnerability against cards like "Vanity's Emptiness" or "Lose 1 Turn".


  • All "Mecha Phantom Beast" monsters that can Special Summon Mecha Phantom Beast Tokens (except "Mecha Phantom Beast Aerosguin") have Tokens appear in their artworks equal to the number of Tokens they can Special Summon through their respective effects.
  • All "Mecha Phantom Beast" Tuner monsters are based on spacecrafts, except "Mecha Phantom Beast Blue Impala".
  • Most "Mecha Phantom Beast" monsters generate Tokens in form of multi-colored holograms. "Mecha Phantom Beast Stealthray" and "Mecha Phantom Beast Blackfalcon" are the only exceptions, in this case their holograms being solid-green colored instead.
    • Their Token-generating devices have simpler designs than the others (as if they were prototypes) and are primarily green-colored instead of black-colored. This may be a reference to their limited Token-generating ability, as their generating effect can only be activated during the Battle Phase in certain scenarios.
    • Both "Blackfalcon" and "Stealthray", along with their respective Tokens are also depicted in the artwork of "Do a Barrel Roll".
    • The same multi-colored light spectrum that these holograms have are also featured in the artworks of "Mecha Phantom Beast Concoruda", "Mecha Phantom Beast Jaculuslan" and "Phantom Fortress Enterblathnir", despite those monsters lacking effects that generate Tokens.
    • According to Master Guide 4 lore, the holograms are made of quantum energy.
