Hi @all,
so, i have maxed his costome and gave him all the emblems.
Here are some facts:
Mana speed:
He is almost fast now. With 7% mana plus (costtume 5 and emblems 2) and a manatroop level 12 (9% mana) he charges now with 9 tiles in offense. (to be a true fast he would need +25% mana which is impossible with manatroop and class bonus only ). But having 9 instead of 10 tiles makes me feel like he is fast since i do have 3 3-match more often than 2-4 match in offense.
I’m not sure if he behaves like an almost fast hero in defense too but i would assume so (never understood how mana gen in defense works)
stats:
i like his costume stats whicht are in the 5 star regions (look at Alby or Tarlak below). His un-costumed stats are looking nice if you take him out to hit the titan … 
(and use the banners for defense up…)
Not sure if i would say he is a 5 star healer now… i don’t have any 5 star healers … but i like him on offense and i try him out in defense like this right now (testing some synergy there):
