What assassin archetype?

I found a grimtrap, and I kinda want to use it when I level up my assassin. Which archetype should I use with grimtrap?

 

I use a mix of trickster and acrobat (for weightless and pirouette), but other people use only acrobat (there is next to no difference since the nerfs of the last update so it is kind of just personal preference). My friend even managed to kill the eye in less than 3 minutes using heavy melee shadestepper.(I would not recommend this though) spell shadestepper is dead in general and only trickster not good. You could play trickster with marked but you have less mana sustain than trickstrobat so I would recommend acrobat or trickstrobat

 

trickster is a good one, btw trickobat(mix of acro and trick) can be used as well

 

I found an oblivion. What archetype would I use for it and is it better?
