That actually looks awesome.
Noble Mahiki because it's four bricks wide and one brick deep. It has a weird creepy face on it that gives it it's power.
Mask of conjuring. Just too dang useful.
I always liked the noble Ruru, it just looks nice (and is available in 15 colors including prototypes and misprints, the most of any kanohi)
Olisi is weird and its power is really creepy.
