Jaden Yuki is the main protagonist in the GX series and this is an elemental hero deck profile.
There are so many "Hero" cards in this archetype with many sub-archetypes like "masked", "destiny", "evil", "vision", "xtra", "elemental", "neos - spacians". This deck is mostly (around 95%) "Elemental Hero" cards.
The main focus of this build is to have easy access to polymerization. Not only that, but most of the cards are kind of searchable with the help of "Giant Rat", "E - Emergency call" and "Elemental Hero Stratos".
The big problem of the deck is that you have to lose your normal summon most of the times, that's why it's important to be aware of the resources you are spending. "Elemental hero Woodsman" can be special summoned in your opponent's turn through "Giant Rat", so in your turn you can recycle "Polymerization" from grave.
The biggest advantage of this deck is that most cards can be used as fusion materials cause there are no "BIG" restrictions. The playmaker of this deck is "Elemental hero Sunrise" whose can help you fusion summon again in the same turn another monster too.
One cool mechanic to abuse vs players that are mostly using mirror forces cards is to, summon "Elemental Hero solid soldier" then special summon from hand "Elemental Hero Stratos" and destroy some spell/trap cards on the field.
Some of my cards are quite slow for the modern standards to give consistency to the deck, some of them are "Giant Rat" and "Elemental Hero Woodsman". To help with this slow paced gameplay, I use "one day of peace", "swords of revealing light" and "storming mirror force".
The main difference of this deck, compared to others, is that I use easier to execute combos by not combining all the available other hero sub-archetypes. Instead I am trying to take advantage of cards like "Skyscraper" and "Elemental Hero Honest Neos" to boost up the attack of my weak monsters. While most of my monsters are level 4, I could add more XYZ cards (Number 27: Dreadnought Dreadnoid or even Utopia engine), but I don't like this approach.
Some cards might not have the best ratios or can be replaced by similar cards. Some of them could be: the second "Skyscraper", the x2 "Storming Mirror Force" and x2 "Lightning Storm" but this is debatable.
