So recently I've been experimenting with the Onion Knight.
At first I thought he was just a psuedo-Zidane, using the same strategy as him.
Now I see him more as a campier (no joke intended) version of Zidane. But with a FAR Superior Ground game.
I'll be showing a video soon of what I mean. But I don't think I've seen many Onion Knights use Firaga, which I'm beginning to think is his best HP attack.
