This is a deck I have been working on:

//NAME: Gadget Cannon
3 Cyber Dragon
2 Catapult Turtle
3 Red Gadget
3 Green Gadget
3 Yellow Gadget
3 A Cat Of Ill Omen
2 Cannon Soldier
1 D. D. Warrior Lady
1 Chiron the Mage

3 Mass Driver
3 Smashing Ground
1 Heavy Storm
1 Limiter Removal
1 Nobleman of Crossout
1 Card Destruction
1 Mystical Space Typhoon
1 Graceful Charity
1 Pot of Avarice

3 Royal Oppression
3 Sakuretsu Armor
3 Reckless Greed
1 Mirror Force
1 Ultimate Offering

This is just like a normal 5th Gadget deck, except it relies on Ultimate Offering getting gadgets out and cannon soldier(and likewise) using them for cannon fire. If you can get a Pot of Advarice while you are in the lead of at least 500 life points doing this combo, its a defiant(spelled wrong) win! This deck still has room for improvement (like a side-deck for starters) and I'm open for suggestions. I really think this deck has pontential. Rating(before and after fixing)?

what do you guys think?

You'll most likely only do about 7k tops with tributing Gadgets, if anything try using Black Ptera with the Cannon Soldier/Ultimate Offering instead it creates an infinite loop.

thanks, now I can make a new type of deck.
I never thought of that, props!

One thing you should know. Reckless Greed is semi-limited.
