Consider an A9 bless. It will couteract Iron skin buff. And if you get into war with a major air user (caelum) it will help. Your pretender will be able to actually do something with those air gems you get. And the air shield is nice vs bows of botulf and allows you to use 2handed weapons without fear of flaming arrows.
The nature 4 bless is also very nice.

order3/sloth 3 seems to be a no-brainer with the low production cost of the Oni's.
