[@Krein] Aaaaah, Evilswarm. I have little experience with Steelswarm, but Evilswarm are hilarious.

Although if you want something really dangerous, you should try fighting Monarchs, or Raidraptors, or Yosenju. The Raidraptors recently got a s/t negate card, and the archetype is becoming dangerously powerful.

My personal main varies, right now it's X-Sabre. They're kinda old-fashioned, but I like the way they roll. You can pull off some sweet combos, and they're masters at brute force.

I use DN, mostly. YGOPRO is sometimes useful for testing decks solo, but that's about it. My DN name, surprisingly enough, is Thewizardguy.
