I'd be interested to see the results from your testing, and whether the pilot knew what he was doing, because your post smacks of hyperbole. Granted, my list did not run Bolt and Grim Lavamancer. These are not widely accepted cards in the list; so it's a valid concern.
Can you build Aggro Loam to beat specific matchups? Sure!
Depending on the build of Zoo, they may just be too fast for you, and to follow up with Fireblast, Bolts, Chains, etc. If you run Devastating Dreams, then it's much easier. Without, you rely too much on Seismic (which is only a 3 of). Zoo also typically play 3-4 Pridemages, which will stop the Assaults.
You're assuming that Aggro Loam draws perfectly every game, and has all the necessary accel, bombs, and removal. This is a fallacy, and doesn't aid any discussion of actual gameplay.
