In for the lolz with new advice regarding today's patch to make f1 high.
As (displacer) raiden, I try to play the ground game as much as possible since I don't have access to the TG fireworks or LRC. I like to keep them knocked down as much as possible and force them to either block low or wakeup attack. When I get to the corner, I'l lleave them standing with a b1,4
To open people up, I like to F1, 4. Now that it's high, I'm not sure what I'll lean on but it'll probably be d1 or d3. I sometimes also like to sit further than neutral and use a f4 to do that lunging kick which is eaten more times than I can count.
Try to keep quick pokes, use your EX armor w/ up superman or shocker and keep them blocking. That way, you give them a quick low poke and pick them right up for a nice combo.
