@A2EZ raiden can be difficult especially since the game isn't patched yet and he can just walk his happy ass through ice clone sometimes but remember he doesn't have a teleport in that variation so try and play keep away and force him into a fireball fight cause you'll win. When you have him cornered and he tries to fly out, let him, and immediately throw an ice ball. Run up and handle business. Slide is always great too but don't be predictable and when he flys at you be ready to punish with b1,2~ice ball. Hope that helps!
