Really the only Deck I use on Master Duel. Basic plan is to get Geartown on field and break it, either with Ancient Gear Balista or Ancient Gear Catapult. Summon Wyvern into Frame, draw Box with Wyvern, draw any 500 defense card you may need or just need to mill, use Frame's effect on field to discard said card or other brick, grab Ancient Gear Fusion, play Ancient Gear Fusion, make sure you have atleast one other Ancient Gear monster in hand, Fusion summon Megaton or Giant if possible, run over your opponent. If your opponent pops Megaton, you got Ultimate golem as backup into normal Golem if it all goes from bad to worse. You'll be searching for a way to get Chaos Giant on the field.
If you need something on the field but dont want to waste Megaton or Giant, Howitzer is a 1k burn immune to card effects; can waste a card effect if opponent isn't paying attention and forces a battle for a Ancient Gear search. Alternatively instead of Howitzer, if you have Geartown and/or Infinitrack Anchor Drill in hand, play Geartown, play Infinitrack to bring two monsters on field, Link-off into Ancient Gear Balista, either add Box or another Ancient Gear monster with Ancient Gear Balista's effect, use Balista's second effect to pop Geatown, use Geartown GY effect to special summon Wyvern, draw box(or another Ancient Gear monster if you already have.) with Wyvern effect, activate Box in hand, draw desired card like Frame or another Infinitrack if your hand is populated.
I recently added Harbinger and Called by because of the Ash Blossom & DBE Spam thanks to Verte being unbanned over here on Master Duel. This might not be a great deck, but it's a good one for what it is at least. Ra is here incase you need more monster removal.
