How to beat Iceman in 5.3.6
This Iceman is under a silent node.
Silent nodes are nodes that do not appear in the description, in this case, Iceman can nullify dexterity. So it really doesn't do much if you evade his specials, he will catch you anyway. So the key to beat him is to use revives.
After a while you will run out of revives. Do not invest in potions as you only have a couple of seconds to fight and his second special will kill you anyway. If you run out of revives, go to the unit store and buy units. Rinse and repeat until it's finally over.
After this fight, there is an Ock Doc under a Lying node.
A Lying node is a node that specifies a buff, but is actually another debuff. in this case, Doc Ock says he has a Special 2 bias. But in reality is a Special 1 bias (he is not lying about the unblockable special 2 though). This Doc Ock shouldn't be that hard, just do not push him beyond his first bar of power or you will regret it.
Finally Green Goblin is the final boss, but he is ok.
End of sarcasm.
