It's Morphtronics! They are kinda difficult to build in a pure way even with all the support they got. This List is made from many years of experience with this Archetype in a way to get the most out of many different Morphtronics with the additional Focus on their Boss Monster Power Tool Dragon. Let's go into Detail:
The Power Tool Path
In general your focus should be to Build up a Power Tool Dragon or the new Braver Dragon as soon as possible and they are not only great Beatsticks with some Tower Functions. They can also get out the Equip Spells from your Deck fast and make your whole Deck more Consistent.
2 Power Tool Dragons equipped with their Equip Spell Double Tool C & D can create a perfect attack Wall while guarding themselves from destruction and negating any effect of Monsters they Battle with 3300 ATK. Note that the C & D equip is only usable on the OG Power Tool Dragon or a Morphtronic Machine Monster with LV4 or Higher.
Power Tool Braver Dragon is missing the protection, that's why you play the Supermagic Sword Raptinus to make up for that. That card feels like written for Morphtronics since it can also change Battle Positions and give an additional Normal Summon. Extreme Life is obviously there to make use of Bravers own negation/battle position change effect to get out Lifestream Dragon, or to just be a imaginary 4k Beater with Card destruction Ability.
At first sight Power Pickaxe looks like a strange addition but think a moment about it. You can use the effect to Banish a Monster from the opponents GY and gain 500 ATK first and then use Bravers effect to get rid of the Equip Spell for his own effect. Maximum Advantage to be made right there.
The Power Tool Mecha Dragons can facilitate additional Draw Power if needed. The Lifestream Dragon is useful if many Equip Spells are already in the GY and/or your Life Points are very low. A very good backup Card.
The one who combines them all is Ultimaya Tzolkin. You will need Lifestream Dragon to summon him in this Deck but once there he can easily summon one Power Tool Monster every turn and get targeting protection too. He even summons Power Tool Braver Dragon and triggers his effect.
To end this Paragraph see the Power Tools as your Main way to get your Deck going up to speed. They are very important for the Morphtronic Strategy.
The Morphtronics arrive
To even summon Power Tool Boss Monsters you need the help of the Consistency bringers, the Morphtronics. They each have a different Effect based on their current Battle Position. There are numerous ways to get to Level 4, 7, 8 and 9 in this Deck and it's a bit up to luck too.
Your 3 different Level 1 Telephones bring the Main Search and Summon Power for this Deck. Morphtronic Converter a powerful Spell helps to set up these Monsters and their effects. They require a Die Roll which makes their effects a little luck based but they are all soft once per turns making big Combos very easy.
But that's not all! The Scannen can search for Spells & Traps, while the Scopen can set up a instant level 7 Synchro summon. Remoten also has applications in that area.
And that's still not all. There's also Gadgets which support this Archetype. Gadget Gamer being the best one, again setting up for a L7 Synchro Summon and searching your Level 1 Starters. Gadget Box is always treated as Morphtronic Card and is easy to access through Scannen and is basically an additional L1 special summon every turn in form of a Token.
With all these tools you will be easily summoning multiple Power Tool Monsters in one turn. But what if I tell you that's not the only way to go?
The Morphtronics Strike Back!
Now with all this Consistency it's obvious you will have Space for another Main Deck Strategy. The Direct Attack OTK! Morphtronic Boarden allows every Morphtronic to attack directly. Boomboxen can attack twice and is a legal target for the equip C & D and Radion is a 800 ATK Boost for all Morphtronics. The Field Spell is another 300 ATK on top, every time you change a Battle Position.
With all that said it's very easy to reach 8000 total Damage through direct attacks to OTK the opponent. When the opponent is to focused on your Power Tool Boss Monsters surprise him with this Backup Plan. This is also highly effective to get past unbeatable Towers and win like that and it's easy to set up within one turn too.
Additional Spice is always good
So the Telefon FTK is well known but not part of this pure Variant... BUT Morphtronic Clocken can Deal 1000 DMG by tributing itself (Or more if you wait many turns) and you can loop that effect a few times too. All depends on you rolling a 2 or Higher and having the means to re summon Telefon and Clocken multiple times. Convoluted for sure but effective nontheless. It does make the Direct attack OTK even more dangerous.
The new Trap Impact Return is a quick effect Speed reborn from the GY or the Banished pile and can shuffle back S & Ts from the opponent on activation. This card is 110% useful I can't even explain it all here.
Staplen can create a Attack Wall like C & D when combined in any way you desire. One Staplen and one C & D = Attack Wall. Slingen is a little Removal Tool. Earfon is the L4 Synchro useful in many Situations, especially to use Braver Dragons effect many times.
So it's the best Deck ever right?
No not at all. All these Combos described can be easily stopped with all the usual stuff like Nibiru and Floodgates. Having to rely and Die Rolls and having some weird downsides/costs on some cards make this Deck miss the Mark to reach the Overpowered territory. It's a Combo Deck in it's Core.
Final Words
Morphtronics are fun. You have many possible Combinations within this Deck and can surprise your opponent with unusual ways and Cards. Try this Deck if you like bigger Combo Decks that aren't super complicated to understand. I really liked them ever since their Anime Debut and maybe you too will find them to be fun to play^^
