Deck Description
I would like to thank RGBfinny for producing this wonderful deck, and also Shiloh for this description. Thank you for visiting, let's go over this deck called: GD-20 Mech. This is a meta deck. Meta decks are decks that represent multiple different slots within the top 32 at a YCS, and often see a good amount of success at a Regional or National level. These Decks are often highly sought after by many different players and dominate formats. This deck uses the April 2025 TCG banlist. This deck was first shared on 2025-04-09 and was last updated on 2025-10-21.
RGBfinny didn't specify if this deck is better at going first or second at the start of the duel. RGBfinny didn't specify the playstyle for this deck. RGBfinny didn't specify how difficult this deck is to play.
The full list is available below, as you can see, the main deck has 40 cards.
I like to use the Dueling Nexus deck creator when creating my yugioh decks. You can use the shuffle button to see what your opening hand might be. Then you can make changes to the deck if you don't like what you see.
