Red, Yellow, and Green Gadgets can be used for the ultimate ongoing +1. When they are summoned (normal or special) they add another Gadget to your hand, +1.
Use this card to obtain hand control (MOST OF THE TIME, whichever player has more cards in their hand will win the duel because they have more material to work with, this is called hand control which is measured in units of -, neutral, and +). Because these cards always add another card to your hand, you will gain hand control on your opponent because you will always be gaining more cards in your hand to work with.
Strategies and game play:
I like to use gadgets in combination with cards like "Tin Goldfish" and "Kagetokage" to obtain fast speed summoning and hand control. when used with the proper cards you can xyz summon powerful rank 4 monsters to the field in a matter of seconds such as "Evilswarm Ouroboros," "Number __: Utopia," "Number __: Shock Master," and more.
Combos with other cards:
Combo with Yellow Gadget, Green Gadget, Kagetokage, Tin Goldfish, Ancient Gear Gadjitron Dragon/Chimera, Rank 4 XYZ monsters, 1for1 card destructors
Ways to counteract it:
Negate it's summoning with cards like torrential tribute
Never ending +1
Fast speed card
Low combat stats
When used correctly, 9/10
