as the falkow guild I challenge you guys to make a mermaid file that's competitive now
just randomly trying them out, and it seems like shufas isn't a total dud if you use her in a level 3 merm rush -> balzelda buff her = mirelia like killer
emana endgame with metia? = bog wyvern never hits xD, decisions decisions on units... but hey who knows if no one plays them, maybe they will make set 10 mermaid stuff OP just for us???
P.S. I just got some Emana seasonals so i'm dying to play merms, but am really scared xD
