Problem is conversion.
For best returns high nwa fae is best choice because they cant retal (many of them is all elite) and have higher def so more epa for ud.
Having off is better choice as i naturally pass offense oriented tms.

When enemy hit one of your tm, best retal is to hit their fae tms as well. i try to hit the biggest fae rogue as retal because enemy mostly will want to have bigger rogues than mystics.
