Is there a really good Club member trainer who could've been an E4 member?
There are few LV 76 trainers. Looking that each E4 member is weak against the one before them (Drayton Dragon is weak to Lacey Fairy which is weak to Amarys Steel which is weak to Crispin's Fire) a logical choice would be something strong Vs Fire. Here are some candidates:
