"Morphtronic", known as "Deformer" (ディフォーマー Difōmā) in the Japanese version, is an archetype of cards used by Leo in Yu-Gi-Oh! 5D's and introduced in Crossroads of Chaos. The archetype includes various Types and Attributes, but most members are EARTH and/or Machine, with several being LIGHT and/or Thunder.

They are depicted in how they "morph" when they change their battle position, which changes their effect(s) and appearance (humanoid in Attack Position; item in Defense Position). They transform into small "electronic" household items, like magnets and mobile phones.

This archetype is related to the "Power Tool" archetype, with some overlapping support arising from their use by the same character in the anime. Some cards in this archetype are designed to facilitate the summon of "Power Tool" monsters and support them once they are on the field.

Playing style[edit]

The "Morphtronic" archetype revolves around manipulating its monsters' battle positions. Each "Morphtronic" Main Deck monster has two on-field effects, and each effect corresponds to one battle position (Attack or Defense), and is only usable while the monster is in that battle position. Most "Morphtronic" monsters and support cards have battle-related effects, with the Attack Position effects being more attack oriented and Defense Position effects being more defense oriented; as the game's power level increased, these battle-focused cards have become functionally obsolete.

A small number of "Morphtronic" monsters, instead of having obsolete battle-focused effects, have effects focused on swarming monsters (revolving around rolling a die and excavating cards equal to the result), and these monsters form the core of the current "Morphtronic" playstyle, which revolves around Synchro and Link Spamming. These monsters are "Celfon", "Smartfon", and "Telefon"; "Scopen" and "Remoten" can also facilitate monster swarming, but are generally less used. Telefon in particular is very potent as a three off, as it is always able to summon another copy of itself from the GY as it is a Level 1 monster and thus its level will always be equal to or lower than the die result of its effect.

While in Attack Position:

  • "Celfon" can roll a die and excavate cards equal to the result, and Special Summon 1 excavated Level 4 or lower "Morphtronic" monster.
  • "Smartfon" can roll a die and excavate cards equal to the result, and add 1 excavated "Morphtronic" card to the hand.
  • "Telefon" can roll a die and Special Summon 1 "Morphtronic" monster from the GY whose Level is equal to or lower than the result.

All three effects are soft once per turn, meaning that multiple copies of these monsters can each use their effects individually, generating significant advantage. Most significantly, multiple copies of "Telefon" can set up an infinite loop of Link/Synchro materials by itself, by constantly summoning other copies of "Telefon" from the Graveyard.

In particular, "Telefon" alone brings enough swarming power to establishe a field of Co-linked Link Monsters, such as "Apollousa, Bow of the Goddess" in the Extra Monster Zone, "Tri-Gate Wizard" beneather "Apollusa", "G Golem Invalid Dolmen" to its left, and any of the "Knightmare" Link Monsters to the right of "Tri-Gate Wizard". "Invalid Dolmen" is especially potent here as it grants excellent protection to its co-link partners, while "G Golem Crystal Heart" and "G Golem Stubborn Menhir" are able to special summon their link material on summon and thus extend combos.. Since "Telefon" is also a Level 1 Monster card, is can be used as material for the Xyz Summon of Rank 1 Monster Cards, giving the deck a way to search a potent Hand trap in D.D. Crow, with "Lyrilusc - Recital Starling. Finally, as a primarily EARTH attribute archetype, "Aussa the Earth Charmer, Immovable" can be used to great effect.

The starter for this swarming-based "Morphtronic" playstyle is "Gadget Gamer", who can search for a Level 1 Machine (which all the above phone-formed "Morphtronic" monsters are), and then Special Summon it and "Gadget Hauler" from the Deck; this immediately sets up a Level 7 Synchro Summon (tying the deck's playstyle to the "Power Tool" Synchro Monsters).

Further swarming can be achieved through "Machine Duplication", "Junk Box", "Morphtronic Convert Unit", "Dimension Dice", "Morphtronic Repair Unit" and "D.D.R. - Different Dimension Reincarnation". "Power Tool Dragon" can be used to search for the latter two.

Due to the Deck's reliance on Special Summoning by card effects, floodgate cards like "Lose 1 Turn", "Summon Breaker", "Skill Drain", "Power Filter", "Macro Cosmos", and "Anti-Spell Fragrance" cause issues for the Deck. The archetype also lacks many first-turn plays after their initial Normal Summon, due to various cards, such as as "Remoten" and "Smartfon", only working if there are "Morphtronic" monsters in the Graveyard. The Synchro and Link Spam variants can also quickly run out of cards in their Extra Deck, and thus may not have any moves to use on subsequent turns. These problems can be mitigated with cards such as "Foolish Burial", "Machina Fortress", and "Urgent Schedule" to fill the Graveyard, or "Machina Overdrive" and "Pot of Avarice" for resource recycling.

As with many Decks, many common hand traps such as "Ash Blossom & Joyous Spring", "Nibiru, the Primal Being", and "Maxx "C"" (OCG-only) are always a looming danger. "Maxx "C"", however, can be a double-edged sword, as players using the "Telefon" loop while it is in effect can force the opponent to deplete every card in their Deck, though at the risk of them drawing into another potentially turn-ending counter. "Nibiru" also does not stop the "Telefon" loop if it is used too early, as any method of reviving a "Telefon" will simply cause the loop to begin anew.

"Power Tool Braver Dragon" is an important end board card, but its power can be reduced easily with simple backrow removal cards like "Harpie's Feather Duster", "Galaxy Cyclone", or "Twin Twisters". With most "Morphtronic" monsters being Machine monsters and being reliant on the Graveyard, "System Down" and "Chimeratech Fortress Dragon" can prove devastating to the Deck, without non-Machine cards present.
