i noticed this format is kinda Dark and Light heavy with all those Dark Worlds and Agents. i think and this would be a good side against them. what do you guys think?

ofc they are

Yes ofc they are but even some cards like prohibiton, mind crush help a lot too

I side a playset of each in Gadgets and Sabers, shuts down so many decks in today's meta.

those cards are some cruel cards, and more or less screw my deck up sideways >.<

if I didn't use chaos decks, I'd side deck 2-3 of each
