Well, IVIasterJay knows firsthand how easily my Iswarm deck can shut down a deck that focuses heavily on special summoning. The only other deck I have that's actually pretty good is the deck I use in real life, and that's a Blue-Eyes White Dragon deck. It special summons powerful monsters like crazy and can apparently go head to head with popular builds like Chaos Dragons, Dark World, and Constellars. At least, that's the impression I get whenever I test it against the decks that come with the Android AI in the YGOPro app. Might not be accurate though, but that's that.
