Iron and ice Monster types

How do we check the names or types of enemies?

I have tried many versions of this
badGuys = hero.getCurrentWave()
for x in badGuys:
if (x.type == “MUNCHKIN” ):

and not sure what names or types of monsters I should be comparing it to? Any help would be great! I am trying to make it so on rounds with the fireballs and phoenix I make more mage towers. I have looked everywhere and can not find how to get their names or types.
