What would your ideal army look like?

Here, please list the units from level 1 to 7 that you would like to have in your castle and army. For example, here is my list:
1-Centaur Captain
2-Upgraded Harpy
3-Great Elf
4-Vampire Lord
5-Mighty Lich
6-Cyclops King
7-Black Dragon
I think this is the most optimal army! What do you think?
