Holy cow you actually made an Epic rarity unit, that's daring. I appreciate you not making a big square and instead using the range augmented even though it wastes characters. I think this is pretty balanced overall, it basically allows you to make 1 mistake, or allows your rush on one side to become super strong. I also like that it buffs nullmage. I think it's balanced - maybe even a bit strong, it's hard to tell. You lose a champion slot but gain instant local positional advantage at some point in the game. Though, Base and maybe + should have better range, they are pretty useless. I think it might even work if it was range 5 at all tiers.
Fear across field: +10 (Instant kill with big range, yeah it's scary)
Surprising move: +10 (It's similar to comet, even scarier)
Aggressive: +5 (It lets you make mistakes which helps aggression, but it mostly affects your side of the field so I view it as more defensive. Moreso, the foe is penalized for being aggressive. It could be used to push hard in some situations, though.)
