Axel_Redd, i've noticed his ns lowers his hitbox to the point he can duck under lots of things, it's a nice tool to go into as someone is waking up as you have so much you can do off it, depending on the opponents choice.
xInfra Deadx, my biggest combo with Freddy is jip, B12U1, U3, ex claw, jip, 22 ground claw, B24... 46%. You're right he isn't much of a pressure machine, but you can overwhelm people once you get a bit of momentum going. My two best mains, CSZ and Kano have better up close tools, but Freddy hits way harder than them. I even feel kinda bad fighting SZ with Freddy, the guy just destroys the ice ninja!
Im also thinking in juggles, you could use B12 into sweet dreams as a kind of reset 50/50 set up.
If I have one gripe, is that I feel input bug affects him quite bad, I hate doing accidental teleports with him.
