I'm not sure what the fuck is going on here, and just what Urza did with his science fair project that causes a gigantic face that's all teeth with a monocle, and trumpets and little whirly-copter things jutting out of the side of the heads, but it looks insane
If you were looking to get that Anvil combo thing going you could be looking at a Hangarback Walker (or similar, Myriad Construct perhaps) to make a ton of little thopters to sac to the Anvil, then cards like Dramatic Reversal, Umbral Mantle, Paradox Engine, Captain of the Mists, Clever Conjurer, Deceiver Exarch, Dreams Grip, Hidden Strings, Galvanic Key, Infuse and Manifold Key (there are others, but you get the idea) can all help to get that Oni-Cult Anvil train running, using Ashnods duplication ability over and over to just ping your opponents to death
