Arcanes are flexible, up to personal preference. Things like [Guardian], reconstruct, reaper are all nice.

Aura is flexible to an extent as well, I use it to force proc avenger and nourish. If you are using something besides avenger nourish, aura can be whatever you want. suggestions include [Ready Steel], [Rejuvenation], [Physique], the armour aura, [Growing Power].

The augments are honestly flexible as well. Other good mods you can use besides [Insatiable] are [Quick Thinking], [Abundant Mutation], [Augur Reach].

[Quick Thinking] will require its own D polarity.
