Ooooooh.... That makes sense.
I think you're thinking of circle. He's talking about down circle.
EC or FP. I can't think of any bad matchups EC has, while FP might have 1 or 2 however (1 being EC).
EC: EC's giga punch is one of the easiest and most reliable 100% hit confirms in the game, and he has a lot of great range moves on top of the fact he isn't bad at all in close range either. Very dangerous character.
FP: Her knights.. These things create the most ridiculous combos that are impossible to get out of once they start. She is the only character that can attack you twice at the same time, and this helps tremendously. If you know what you're doing, once you have about 40 AP and you start a combo, you can kill someone at the end of the combo. On top of that her level 1 AND level 2 both have good, reliable 100% hit confirms, and her level 2 can kill you twice if you aren't careful.
