Call it crazy, but the Armed Dragon Thunder theme's becoming a big sleeper hit. And with more duelists working on the deck, it's actually getting more competitive! The deck's biggest problem was card economy, but Sam's newest build solves a lot of that. It's got all the same combo-starting tricks with Armed Dragon Thunder LV3, but it's innovated and optimized to skip straight to Armed Dragon Thunder LV5, and that means fewer discards.

The key is Artillery Catapult Turtle; you can Normal Summon it and tribute it off to Special Summon Armed Dragon Thunder LV5 straight from your deck, making more explosive combos more efficiently. From there, Sam's build leverages the original Armed Dragon LV10 and Armed Dragon LV10 White to go into Superdreadnought Rail Cannon Gustav Max and Superdreadnought Rail Cannon Juggernaut Liebe, winning games in just one turn.

Underrated cards like Armed Dragon Blitz and White Veil hold it all together. You can see the card-by-card breakdown and combo tutorials in Sam's latest video.

This version of the deck is way more consistent since it runs Artillery Catapult Turtle for three more combo starters. It also has more ways to play around your opponent's defences, and it's more dedicated to going second; that makes it easier to just plow through and take wins. 

Surprisingly, this casual little GX strategy may prove to have real teeth. Check out the full deck list below and see for yourself.
