Army composition question

[BobMaster]

Hey all,

I recently came across Armored princess, finished it and read there was one beore it called The Legend, so I went and get it aswell and here I am :p

So I have some kind of a problem.
I'm aiming for a animal only army, at the moment my army consists of:
Cyclops
Ancient Ent
Alchemist
Giant
Royal Thorn

I thought of changing the center 3 for the 3 different dragons, but I have been reading some on this forum and it seems they won't be usefull the entire game (haven't been to demonia yet, dont like to swap and switch my army all the time).
So do anyone have some suggestions for me, or just some army building tips in general would help as well, thanks

Greetz,
BobMaster
