"Morphtronic", known as "Deformer" (
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. Despite their appearances, "Morphtronics" are not all Machine monsters and they also represent a wide array of Attributes.
"Morphtronic Cameran" appears as a character in Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator, and both "Morphtronic Celfon" and "Morphtronic Remoten" appears in Yu-Gi-Oh! Duel Arena.
The fastest and most consistent variant is the Synchro Spam variant. The idea is to make use of "Celfon" along with "Machine Duplication" to summon various Tuner monsters, of which the deck has several. "Scopen" makes summoning Level 7 Synchros very easy, while "Smartfon" can be easily summoned to extend plays and add consistency to the deck. "Crystal Wing Synchro Dragon" can be summoned easily by using both "Scopen" and "Smartfon".
Due to the rule changes made when introducing Link monsters to the game, a Link monster must be summoned first. "Missus Radiant" is a particularly easy one for the deck to summon, which can be combined with "Gaia Saber, the Lightning Shadow" or "Proxy Dragon" when trying to summon monsters that require multiple Synchros as material, such as "Shooting Quasar Dragon", "Stardust Sifr Divine Dragon", or "Cosmic Blazar Dragon".
Alternatively, the Red Dragon Archfiend Synchro monsters can be used, as the effects of "Hot Red Dragon Archfiend King Calamity" and "Hot Red Dragon Archfiend Bane" summon from the graveyard, circumventing the rules. If this is done, one must either use "Scopen" to summon a Level 7 Synchro (or use "Machina Fortress") then use "Lantron" or "Smartfon" to summon "Scarlight Red Dragon Archfiend", or use "Scopen" to summon "Ancient Pixie Dragon", as it is the only Level 7 Synchro the deck can summon to satisfy the non-Tuner requirement.
Use of cards like "Junk Box", "Repair Unit" and "D.D.R. - Different Dimension Reincarnation" allow the deck to make a large amount of additional summons, and therefore more Synchro Summons. "Power Tool Dragon" can be used to search for the latter two.
The combination of revival spells and the effect of "Celfon", along with extra draws from "T.G. Hyper Librarian" can result in a full field of Synchro monsters.
Prior to the introduction of Link monsters, it was possible to summon "Shooting Quasar Dragon" using only "Celfon" and "Machine Duplication" in hand by using the 3 "Celfon" to summon 2 "Scopen" and "Lantron" or "Smartfon". A combination of revival spells in hand or summoning "Remoten" to banish a "Celfon" to search for "Smartfon" can be used in the event of unlucky rolls.
Due to the deck's reliance on special summoning via revival spells and monster effects, cards like "Lose 1 Turn", "Summon Breaker", "Skill Drain", "Power Filter", "Macro Cosmos", "Anti-Spell Fragrance" and "Imperial Order" cause issues for the deck, among others. Effectively, most popular and unpopular floodgates. Cards like "Twin Twisters" and "Accelerator" must be used to clear these cards from the field first.
Additionally, the archetype lacks any first-turn plays aside from having "Scopen" and a Level 4 monster, or "Celfon" with "Machine Duplication" in its starting hand, due to revival spells, "Remoten" and "Smartfon" only working if there are monsters in the Graveyard. One can mitigate this by using cards like "Foolish Burial", "Machina Fortress", or "Brilliant Fusion" with "Gem-Knight Seraphinite".
Cards like "Maxx "C"" and "Ash Blossom & Joyous Spring" can force an early end to the player's turn. However, notably, "Ghost Ogre & Snow Rabbit" does not. This is a common misconception due to "Ghost Ogre" stopping the effect of "Gagaga Cowboy", who has an effect similar to a "Morphtronic" monster. However, "Morphtronic" monsters check their battle position upon effect activation, not resolution, so the effect will still apply as normal.
As most good "Morphtronic" monsters are Machine monsters, "System Down" is an extremely powerful counter to the deck, especially due to its reliance on revival effects. "Chimeratech Fortress Dragon" can by used to strong effect against all but the Synchro Spam variant. "Power Tool Dragon" and "Morphtronic Forcefield" cannot prevent this because they are all being used as Fusion Materials.
The Equip variant can be hampered with cards like "Dark Highlander", "Eternal Rest", "Really Eternal Rest", "The Emperor's Holiday", "Armored Glass", "Armor Break", "Disarmament" and "Collected Power".
