Forum:Chaining/Timing Question

Earlier, I was dueling someone and the field was set-up like this:

I had a Caius the Shadow Monarch & Majesty's Ruler on the field, and I attacked his Evilswarm Exciton Knight with Caius. It was his only monster on the field.

He then activated his only facedown S/T---Breakthrough Skill---and targeted my Majesty's Ruler to negate its effect. I'm not sure when he activated it, whether or not it was in response to my attack (but I assume so).

Accordingly, I chained a Forbidden Dress to his Breakthrough Skill, and at some point, he detached an XYZ material from his Exciton Knight and said that thanks to the way the chain resolved, I still lose everything on my field thanks to his monster's effect?

How did that work, exactly?

If my Majesty's Ruler's effect prevents the activation of effects, his Evilswarm monster having an ignition effect (clearly stated on the card), then how did he manage to activate it at all?

Because from my understanding, since it resolved backwards (My Dress protecting Majesty from Breakthrough), he shouldn't have been able to use its effect in any way - thanks to Majesty's continuous effect and breakthrough never touching him? Was there something I missed? 01:06, May 11, 2014 (UTC)
