Sheesh, that must be one of those newer archetypes with whacky effects that could probably cream me in 1, 2, 3 xD. Never even heard of them (save for maybe one or two), but I'm just running Archfiends as my secondary deck. Archfiends are fun, but if need be I'll make a new Archfiend deck just to make it up to par with whatever others are going to be using...
