Hint: Cheap Strikers:
The two cheapest (most effective) Strikers available are Dark Billy Kane and Dark Yamazaki. These two Strikers jump straight to your opponent, attacking in the air, then post them up in the air to attack. Billy Kane will post the enemy higher than Yamazaki, but may do more damage. Yamazaki will not only post the character up, but will toss him in the air slightly when he is through. With either type, have your character pull off some devastating Super Moves.
