Another TOA 50/6*ing question..

Here's my box: https://swarfarm.com/profile/Inverse/

So.. Yeah. I'm stuck at TOA 50. Goddamn Woonsa and his horrible little gang. Tried lots of different combos and nothing seems to work. Can anyone suggest anything to help?

Also, who should I 6* next? I've got enough fodder to make two 6*s. I was thinking Arnold or Hwahee or Galleon, but I'm open to suggestions.

EDIT: Doesn't matter about TOA 50. Managed to do it kinda easily. I think I was just being stupid before hahaha.
