I just realised that Asian White Birch is such a great support, 140% weak damage/str for pierce attacker is pretty good, plus x2 guts allowing me to buy time for a potential slow team, she's a bit restricted but that's okay I guess, unfortunately I don't really have a strong pierce attacker atm.

I think for now it's pretty much impossible for me to beat level 200 Castle, I will wait for Zinnia then comeback later on.
