I've always found that aggro (or at least low curve midranged) is the best thing to be doing after cutting down on the number of Nekrataal effects I had. If you don't have ample early interaction you just kinda die. Even if you don't die by t5 aggro still has ridiculous options that force removal (or even just outvalue you). Then you need to actually end the game before they find enough reach to kill you.
Do untapped duals even help aggro more than other decks? If an etbt dual causes a deck to miss a play vs aggro they're probably losing at least 1-2 mana, while in aggro you probably don't lose any mana. There's also at most 1 pain land aggro can play, while decks with splashes can play 3. Obviously aggro's mana is bad for 1 drops, but that's why you autopick stuff like Gemstone Mine or City of Brass.
