Just spam goblins and rage with a few staves of holy empire equipped.
If you don't have any Staff of Holy Empire, you can use the strategy below, but it's much slower.
Send a mix of shark men and puppy dragons. The enemy will think that the shark men will counter their elite dwarves due to water > fire, so they'll only send out dwarf sharpshooters, which are pretty much cannon fodder for puppy dragons. Because you are using low grade units, the AI will not think to send any of the dangerous higher level units that can hide behind the hero.
Once you hit the population cap, replace the dying shark men with more puppy dragons. By the time the computer will think to send out elite dwarves, there will be too many puppy dragons for any of the elite dwarves to survive more than half a second.
