Anyone who can hide or provide enough decoys or teleport or dimension hop or possess TSB also > 8 gates Guy. Hell, you could add a few more things as opening the gate isn't an immensely fast process.
GL landing the genjutsu btw. Even if it hits. Guys body is literally being torn apart from the inside so his pain will break him out of it and you'd have to deal with his chakra surge as genjutsu can be broken by stopping your chakra or overwhelming it so OP is wrong. :bdpf: fail, troll, bait, rustle attempt thread is a fail.
