I've been meaning to post this thread for a while but never got around to it. I have a few things with Displacer Raiden that hopefully some of you Raiden players out there find useful or may have not known about.
Meter Building and being +1 on Block after F+2,2+4:
The good thing about this is not only does it build you meter on block, but it also ALWAYS gives you positional advantage by allowing you to choose to teleport behind your opponent or in front of them. This leaves Raiden at +1 on block. It's also not too hard to confirm on block and teleport.
Safe B+2 Overhead options:
For the characters who can punish Raiden's B+2~Shocker on block, there's an alternative you can do against them in Displacer by using B+2~EX teleport or B+2~Away Teleport. Many characters won't be able to punish the Away Teleport after the B+2 making it a good option for hit and run 50/50 strategies in Displacer. B+2~EX Teleport is also 100% safe against anyone in the cast.
Combos after B+2~EN Teleport
These are some conversions you can do after B+2~EX Teleport. The first combo requires stamina. The second combo doesn't require any stamina. You can also choose which side you want to teleport to and combo afterwards. Once you condition your opponent to respect your other follow-ups after B+2, you can use this and get away with it most of the time as they will not expecting it or looking out for a different link on your B+2.
Guaranteed Jailing 50/50s on Block
If Raiden does his F+2,2+4 string and links his EX teleport afterwards, he is at so much advantage that he can go for a guaranteed 50/50 attempt. Raiden's Overhead (B+2) and Low (B+3) both jail and cannot be interrupted afterwards. He can either go for the safe, low damaging reward, or the high risk big reward to close out a round.
13% Guaranteed Chip Damage on Block
Utilizing the huge block advantage on F+2,2+4~EX Teleport, Raiden can continuously loop this string into more EX teleports to create a total of 13% guaranteed chip damage on block for three bars of meter. Perfect for closing out a match when you have meter left over and tag your opponent with F+2,2+4 on block. You can even do a few reps of these and then on your final EX Teleport go for a guaranteed 50/50 attempt to finish off a round.
