Ok, let me make a cheaper deck for you.(if i put xX, that means however many you like.)
You need field cleaners so let's start with:
x1 Torrential Tribute
x1 Breaker the Magical Warrior
x1 Mystical Space
x1 Heavy storm
x1 Giant Trunade
xX Trap stun
xX Fissure
xX Smashing Ground
xX Trap Hole
xX Exiled force
xX Sakuretsu Armor
These cards are needed to stop opposition to your main attack which I like to call "Gadget Swarming"
For this you will need:
x3 Each "Gadget"
x2 Ultimate Offering
x1 Limiter Removal
xX Beast King Barbados
The idea is to clear the field using the above^ cards or Beast King, then use Gadgets' ability to bring each other into the hand, summoning them all with Ultimate Offering.
This tactic can be reinforced by Limiter Removal (possible OTK) and burn cards to damage the opponent. Gadgets can be reclaimed with Pot of Avarice.
Until the time you can activate this combo, stall cards are needed like:
Spirit Reaper
Magical Cylinders
Negate Attacks
Threatening Roar
All the cards I've meantioned are cheap and in common print(sans Beast King) so it's not too hard to make. Hope you have fun with this deck.
