Been testing the deck on DN all day today and it's been doing really well. It's one of my favorite decks to use. What do you think? Any fixes?

well it depends on what you need help wit go into the chatbox so we can talk and not spam the post

If I was you, I'll run more Ancient Gear Gadjiltron Dragon and run a different engine. It may be too slow for the current meta.
Maybe run a Machina Engine?

But still, nice beatstick deck. ^^

not really fond of malefics. never liked them never will

Never was fond of anti-meta/skill drain type of decks. A lot of people who hate on popular top tier decks usually only play anti-meta decks, but the reason they like to hate on meta is "meta takes no skill, all luck and auto-pilot." Really though, how much skill does it take to play a skill drain deck... you play skill drain and then beat over your opponent's tries at defending themselves while they wait to draw a mst... Honestly takes less skill imo to play anti-meta than it does to play meta.

Running 3 dark birbes is a no-no. take it oouuttt. I'd also run 3 Rai-oh and 2 maxx "c". They're both really viable in this format, possibly the best answer cards this format since so many of the popular decks this format search like a mofo(DW has Snoww, Heroes have e-call, stratos, R.O.T.A, Pot of Duality, Madolches and Prophecy search ALL THE TIME, and Geargia has a bit of searching too) and they all have a ton of inherent special summons(Grapha in DW, Xyzs into Heroic excalibur, Blade Armor Ninja, and bubbleman for Heroes, etc.)

Only one Ancient Gear Dragon is necessary since Geartown pulls it from anywhere except banished. If it gets banished, oh well, he's not exactly the boss of the deck.

Run BLS? you might not always have skill drain and if you're using 3 Rai-Oh and 2 effect veiler with those darks, wouldn't be hard to use at all. Always good to have a back-up plan in a deck that revolves around a continuous trap effect.
