Assassin/Ninja Help What Powders?

So, what powders should I use for this build:

Aries [1 slot]
Mummy's Rag [0 slot] AND Angel Robe [1 slot]
Legs of Desolation [1 slot] AND Sagittarius [3 slots]
Wind Mimic [3 slots]

Wall Breaker [2 slots]
Rewind [2 slots]


The build is mostly earth/air.

Might be a good idea to use Rage since it's gud, but idk

 

Use air powders on all the armor that can have a passive special and then put powders to counteract defense loss so that you are slightly tankier. Put water powder on rewind and earth on wall breaker

EDIT: also instead of mummy rag use chestplate of ineptitude because it gives lots of hp and gives plus two tier atk speed. This also means that you get another powder passive. I suggest earth 6 on this as it will boost your damage by a ton. Also put that on sagitarius too so that it counteracts the negative earth defense a bit. This will make you do 2% more damage per 1% of hp lost which is VERY op your powder special will do near 10k earthquakes on wall breaker and you'll have good ways to do huge damage with the rewinds water soecial
