Introduction
Gaia is a fusion deck piloted by DM character Yami Yugi. it uses enhanced versions of Loading... , Loading... and Loading... . It was a top tier deck 3 years ago when the structure deck [Rise of Gaia] was released and now a new support released this year in Majestic Magic and Spiral leading to the Dragon Champion which creates a connection with Loading... .
Skill
Loading... leading to Loading... ... This is the new skill for Gaia. It allows you to special summon any monster from hand, meaning you can play handtraps such as Loading... and Kaiju monsters ( although its main purpose is probably to allow you to summon Loading... ). The first effect summons Loading... from hand or deck. The second effect is for turn 2 onward while the opponent have more cards on field than you, from outside the deck add Loading... and summon Loading... .
Core cards
Gaia the Fierce Knight Monsters
Warrior monsters with different levels, attributes, ATK and DEF.
Gaia the Magical Knight (3x)
You can normal summon this without tributing if you have no monster on field or the opponent have a monster with ATK >= 2300. On summon it summons a level 5 dragon ( usually Loading... but there is more targets ) from hand or GY. Play it at 3 copies because you want to open it for the combos ( mentioned later ) and follow up .
Soldier Gaia the Fierce Knight (1-2x)
Quick effect it tributes any fusion monster ( except Loading... ) to summon itself from hand. On special summon it changes 1 attack position monster to defense position, good to prevent lethal or to inflict massive piercing damage. On field it tributes itself to add Loading... or Loading... from deck to hand.
Gaia the Fierce Knight Origin (0-2X)
Only play this card if you don't own many copies of Loading... .
