Thinking on this, I think I agree with DMUA here.
Teleportation with speed equalized is really busted, it's basically what Blackjack used to get to this point in the first place, she has other abilities that help and would be useful in a different kind of fight, but Left being able to spam teleportation with literally no drawbacks and the fact he can teleport out of her telekinetic grip and to easily dodge her projectiles lead me to believe this is very much an obvious win for Left.
I kinda imagine a
Ryo Shimazaki moment where
Left teleports into Blackjack's force fields and hits her.
Sadly I don't think Blackjack can do anything here to beat Left, best case scenario she could try to trade hits with him, but she would need to know where he's gonna teleport at all times and trade each time and maybe she could win but that's super unlikely.
