Necromancer Shinnok.
Call me biased I don't give a FU--
But in all seriousness, his other two variations clearly outshine it, Flick being -8 on block... (I mean, -4 was okay. I still do not see the need to increase the recovery by 4 more frames.
So the only thing he can sorta do for pressure is 31 XX EX Flick/EX Amulet? Might as well do Hellsparks.
Not to mention Flick doesn't hit the opponent well, I have had people literally jump for joy against Summoned Fiend, Falling Hand might be one of the worst unblockables in the game. Combo specific shit on male/female/giant characters. It's like fighting with Shinnok's base toolset sometimes it's that bad.
So, I mean Jason is clearly a character who is HARDER, but going off of personal experience I find Necro Nok to be lacking, his worst variant, and not very good. Though you never know what could be discovered.
