Info on Trampling.

You can avoid being trampled only if you are of same or bigger size than the trampler. To view the size of the unit numberically, right click on unit, and right click on its hp. It'll list, among different things, the size of said unit.

I think the Juggernauts are size 6, so you need size 6 creatures to prevent the trampling effect. Of the fire summons though, only the Kings, and I think fire elementals, are size 6. Of Blood summon, the demon lords, and some cross-breeding units are size 6. So your options are somewhat limited.

As for fliers, flying do not offer any protection against trampling I believe. As long as they are of smaller size than the trampler, they will get trampled. Etheral helps, however, in that ehteral creatures are more likely to avoid the trampling damage.

Back to the Juggernauts, they are listed as magical beings, so any spells (Opposition?) or items (Moon Blade maybe?) targeting specifically magical beings may be of interest here too.

Hope this helps,
