A deck with a "protect the castle" type of strategy. Only one copy of Vylon Epsilon is really necessary cause you will most likely only be able to summon one throughout the Duel. Power-up and protect your Vylon Epsilon by putting all Equip Spells on him.
You need to summon Vylon Epsilon immediately during your first turn and keep him on the field. His excellent base stats means, given the opportunity, he can deal a good amount of damage to your opponent. His first effect protects the Equip Cards that are attached to him, which in turn protect and strengthen Vylon Epsilon. With his second effect you can destroy one monster your opponent controls per turn, without worrying about the cost because of this deck's amount of Equip Cards and search ability.
Since your Spell/Trap Zone can only hold 3 Equip Cards the cost of Vylon Epsilon's second effect will also help you clear space for the Equips you currently need.
If you draw any of your level-3 Vylon Tuners you should be able to Synchro Summon into Vylon Epsilon on your first turn. Normal Summon your Tuner monster and use Labyrinth Builder to put Labyrinth Wall on the field for a first turn Vylon Epsilon.
Depending on the Tuner you use you can gain different kinds of effects. Vylon Cube lets you search an Equip Spell from your deck. Vylon Stella can equip itself to your Vylon Epsilon. Vylon Stella's effect is not really that useful on Vylon Epsilon so she might be the the best cost for Vylon Epsilon's effect.
All these Equip Spells are to be put on Vylon Epsilon which protects them and can be used as cost to destroy an opponent's monster. The Vylon Equip Spells can then search out more Vylon Equip Spells when they are sent to the graveyard which means you never have to worry about running out of cards to use as cost.
Power of the Guardians protects Vylon Epsilon from destruction and can steadily boost his attack. Vylon Segment protects Vylon Epsilon from opponent's Monster and Trap Effects. Vylon Filament protects Vylon Epsilon from Spell/Trap Effects but only while he is battling. Vylon Component lets Vylon Epsilon inflict piercing damage, which is helpful for dealing damage when you only have one monster on the field.
Enemy Controller can be used to stall when you don't draw your Tuner. But it's most practical use in this deck would be to change your opponent's battle position for Vylon Epsilon to maximize damage. If Vylon Epsilon is equipped with Vylon Component, you can change an opponent's monster to defense position and inflict piercing damage.
