Armed Dragon is an archetype of Wind Dragon Level monsters introduced in GX, and like most things introduced in the GX era of the TCG, it wasn't very good. However, they have recently gotten a retrain series called Armed Dragon Thunder, which entirely remove the mechanic of them Leveling Up after certain conditions have been met, and are instead able to send a monster from your hand and that card to the GY to special summon an Armed Dragon monster of the step up or anything beneath(i.e. LV5 can summon LV7 or below).
For the decklist, we have an Armed Dragon package of 2x Thunder LV10, 1x LV10 White, 2x Pile Armed, 3x Thunder LV7, 3x Thunder LV5, 3x Thunder LV3, 3x Flash, 2x Lightning, for the rest of the Main Deck, we have a Handtrap lineup of 3x Ash Blossom, 3x Maxx C, 2x D.D.
