Cost Down and Amarylease can be used together or individually to ease the summoning of Ancient Gear Reactor Dragon.

still monstrous in 2021, need ancient gear gadget, konami
In a time where they're properly hitting the money cards, it is puzzling why this bs is still entirely free. It's so absurdly broken I can't even begin to describe. I really am sick and tired of seeing goddamn 3 of this 🔥 summoned in a SINGLE TURN every duel. The way it bypasses EVERYTHING including even monster effects ANYWHERE is just so bizarre. I never won against a Reactor Dragon deck other than it bricking.

I don't see them too much any more, but one randomly show up every now and again. I'll take it over fighting Vagabond with Lava Golem stall decks.

I don't know how to make them miss timing. Removal for the field spell (Cosmic Cyclone) isn't searchable quickly.. it just becomes all about luck and I can't defend myself quickly enough. I tend to try the "don't set anything" strategy to avoid Double Cyclone but they can just release Wyvern or the AG Castle (thankfully the Vagabond doesn't get this) and start all the triple Reactor Dragon BS.

Could you please tell me how you will by pass a Sunsaga, Chidory, Madame Verre, Pugatrio+invoker? Because once your opponent sees your character will just summon one of these and just laugh.

I hate BS comments about "year". They can summon three huge beaters that bypass everything in one single turn. And it's a deck bizarrely untouched by the banlist other than a skill nerf in late 2017. Wow, if you laugh and think you win simply by seeing the opponent's character, you're in for a big fall. None of those monsters are invincible.
I have been utterly destroyed by this guy in Ranked a few times before I managed to get Jaden/Yubel. Now I can at least win 3/5 Ranked matches using my Neos Fusion/Neo-Spacians deck.
I have a fast way to bring this card out without any ancient gear related cards

I hate this card too. But in business as long as this AG deck can produce so much money to komoney what for they limit this golden eggs for the company. Its simple just buy with real money and easy to get kog. Thats why komoney can print decks as much as they can like this for the future. Its only business bro. Haha...
Ban this 🔥.It is ruining the game.Nothing can defend against it.

Or pray that you can get one if Konami gives us a UR dream ticket like the ones for gx and 5ds release
lol it can be destroyed with golden castle
Does dimensional prison work on this card? It just says "when it attacks", not if a attack is declared. So when they say "I attack!" with reactor dragon, can you still use dimensional prison to banish it?

But why? As long as the attack isn't happening yet, then shouldn't it work according to the card text? Or is declaring an attack considered the same as actually attacking?

Duel links doesn't differentiate between the two.

As soon as the swipe is in then it's attacking. No window.

In short, it's binary. You attack or you don't attack.

Okay. I got confused at first because both of the cards' text make it look like it could be two separate situations when you read them. But I should have known that would be too good to be true.

Dimensional prison is targeting the attacking card the moment you carry out the atk ( u move the red arrow ), meanwhile reactor dragon eff make the ATK cant be interupted the moments he ATK.
just get higher than 3k atk and ancient gear becomes a joke
