So basically I built a morphtronic spam deck. The general idea is very simple:
Step 1: Summon celfon
Step 2: Cycle through you deck and summon a ton of monsters eventually making your way to two telefon and getting cannon soldier out (usually through the means of saryuja)
Step 3: Have cannon soldier do it's thing by looping the two telefon (they can just keep summoning each other so cannon soldier will win the game just by sacrificing them).
Step 4: Win the game.
Yeah, so basically it's just that, the only difficulty is getting this setup, which is what the rest of this deck is for.
Here's the rundown
3 Morphtronic Scannen
Scannen has two helpful search targets and declutters your hand to summon itself, it also recycles cards and sets monsters for your celfon.
1 Gadget Hauler
This card is simply because of gadget gamer, it has no other real purpose.
1 Cannon Soldier
Cannon Soldier is the main card here, it's going to need to eat 16 monsters before it wins the duel but it can get this easily thanks to telefon
2 Morphtronic Staplen
Level 4 morphtronic name
1 Morphtronic Slingen
Level 4 morphtronic name, it destroys something too I suppose.
1 Morphtronic Scopen
Scopen can summon the level 4 names and it becomes level 4 in defense position.
2 Morphtronic Remoten
Remoten can recycle cards and search for morphtronic monsters, particularly smartfon most of the time.
3 Gadget Gamer
You can snag celfon and summon hauler who's good material f9r some cards.
3 Morphtronic Celfon
You'll be using this card a lot, and I mean a LOT. This card is pretty much the backbone of the deck and you'll be looping it for most of your gameplay.
3 Morphtronic Smartfon
Smartfon has the bonus of being A: self summoning and B: a tuner, it's conditional search is also neat card advantage and you'll also use this card a lot.
2 Morphtronic Telefon
You only need 2 Telefon to pull off the ftk, they both summon the other one and get tributed by cannon soldier. You'll pull both of them out of your deck pretty easily sooner or later.
3 Morphtronic Repair Unit
Summoning Celfon again is most of the reason you play this card, it's not a hard opt and it's searchable through Scannen and Smartfon.
3 Dice Dungeon
Searching Dimension Dice is a valid reason to play this card, I'll explain later but it's also a field so that's handy.
1 Sacred Scrolls of Gizmek Legend
This field is able to grab Smartfon or Telefon but it's only really there because it's the most valid target for ancient fairy dragon. However it will mess up the ftk if you don't get it off your field afterwards.
1 Dimension Dice
This card summons Celfon from the deck for a tribute, you only need one because there's a handy field for grabbing this card.
3 Junk Box
This card is pretty much just a monster reborn for morphtronic and that's the only reason I'm using it.
3 Machine Duplication
Celfon and Telefon are both valid targets for this card, that's a good enough reason to use it.
3 Morphtronic Converter
Converter serves the purpose of either dumping Celfon out from your deck or summoning cannon soldier from your hand if anything. Regardless of what variant of morphtronic you are running you want three of this incredible card.
1 One for One
Summoning Celfon or Telefon from the deck is reason enough to run this card.
1 Centur-Ion Legatia
This card is literally only here because it draws a card. I know it's a dumb reason but this deck is mostly going through your deck and every little bit helps.
1 Baronee de Fleur
Baronee is a boss of great quality and is your backup in case something happens to your ftk, that's a good enough reason to use it.
1 Ravenous Crocodragon Archethys
This card can grab some draws and provides interruption if needed. It's also insurance if you land with a scrolls so you can get the ftk without it messing you up.
1 Ancient Fairy Dragon
This card has some important purpose in this deck, you'll use it to replace dice dungeon, grab scrolls, and summon cannon soldier from the hand if needed.
1 Coral Dragon
At this point I am going for as much draw power as possible. It's a tuner with a convenient level so that's neat.
1 Stardust Warrior
This is only here to draw a card, it's level six is good sometimes too though.
1 T.G. Hyper Librarian
This synchro monster is what will keep your turn from ending early, it's continuous drawing can grab combo pieces or parts of your endgame.
1 Naturia Beast
Beast is summonable in this deck and infinite spell negates will go a long way in this game so I run a copy to build a secure board in case my ftk is unavailable to me.
1 Herald of the Arc Light
Being both a negate and a living floodgate this synchro monster is a backup in case you, for some reason, can't do the ftk.
1 Formula Synchron
This monster is both easy to summon and a draw in this deck, you'll probably end up summoning it at some point every duel.
1 Beatrice, Lady of the Eternal
This monster is summonable in this deck and you don't necessarily need both Telefon on the field to ftk someone, just one, so I ran it.
1 Gear Gigant X
Gigant is here to grab cannon soldier and is going to be quite important in your gameplay as you want to at least ensure you get it.
1 Saryuja Skull Dread
This excellent link 4 is a hand reset and a way to get the cannon soldier out of your hand and on the field where it's ready to kill your opponent.
1 Linkuriboh
This card is to just get Celfon off the field and in the graveyard ready for revival, it's insurance if you will.
1 Apollousa, Bow of the Goddess
Another insurance against a failed ftk, this deck can consistently get the ftk but being able to afford insurance if the ftk fails is probably one of the best traits an ftk deck can have, there are ftk decks that if the ftk fails it's just a surrender on the spot and that's not fun for anyone involved.
Overall this ftk is a silly strategy, you'll probably be able to do it quite often as the deck is quite good at getting its resources. And yes there's room for optimization, but you can get to the ftk pretty consistently and that's what I mainly care about.
