Morrigan
Morrigan is one of the best characters in this game. She has a high speed and can do a lot of combos due to that. Her supers can do a lot of damage. This allows you to do a lot of damage fast making almost anyone an easy kill. Her speed allows you to play her as a combo character, but her good feature is that you can also use her as a keep away if you need to. High recommendation for those who are looking for a balanced character. One downfall though. She can't combo into most of her supers.

This is a nice little basic combo that is her only link into a super. This does 2 crouching kicks into a Silhouette Blade. Fairly good damage, nice and fast though.
D+FP, WP, WK, MP, MK, WK, (UF+WP, UF+WK, UF+MP, UF+MK)
This combo is an infinte that can be done easily with some practice. First you start a normal air combo then drop a bit, then use the WK that comes before the brackets. After that, you'll land then go straight into another jump, this time a regular one. This time you do a 4 hit air combo, but slow down the timing between the MP and the MK so that it hits them up a bit for the next jump and 4 hit combo. Keep on repeating this and you'll win in no time.
