Man the Lyn Abyssal was annoying

So many movement/positioning tweaking so enemies would move in different ways. And the key in the end was giving 4* lv 40 Sylvia Fortress Def 1 and CD3 seal (I'm pretty sure Olivia just works without any of that, but I'd rather use Sylvia than Olivia) so she'd have more def than B!Lyn on enemy phase causing one of the fliers to not bunch up next to 3 other units which allowed me to take out those 3 without anyone being in range of attack on enemy phase.

Also I loved that Blazing Thunder damage from Rein meant Lyn got taken out by Vantage DC Bonfire Ares before she could even attempt to attack!
