User blog:Warlokthegreat/I need a better healer

(Just so you know, I am typing this on my mobile, so Autocorrect is a problem)

So, my current team is (in order of favorite unit)

1. Rebel Angel Elsel (leader, star blade) 5*

2. Dark Tunes Eric ( Moonlight Lantern)5*

3. Battle Girl Ophilia ( Demon Rifle)4* (5* on Tuesday)

4.  Saint Maria ( Brave Crest)4*

5. Ice Queen Selena / Ice Keep Copra(Poison Shiv/Flesh Armor)both 4*

IN slot 5 I want ice Keep Copra, but I don't have enough cost slots for it. I Also need a way better healer,  since the healer I have is a captured unit that I've maxed out. I really need a better healing unit. My whole team is dedicated to taking the least amount of damage,  with my leader skill making me immune to status debuffs, a healing unit, and eventually a brave burst that cuts damage in half. Anybody got an idea for a better healer? Maria is just not cutting it  right now. Also, I want to switch out one of these units with Kajah, but I can't figure out which one I should switch or if I should even switch at all.

HELP ME PLEASE!
