Suggested by Sonic Witchfire has some basic magic to augment her abilities but it won’t be enough against Brandish. While Brandish is hardly one of the stronger Fairy Tail fighters, her size manipulation is dangerous and she has some basic energy projection. Witchfire can’t burn hot enough to overwhelm Brandish in time to claim victory here. Ultimately she will just be on the losing side and just doesn’t have the tools needed to win. Brandish wins.
