I like Blade a lot. My only thought is how does Supernatural Weaponry work against another figure like Major X17 (if it was on an Undead or Lycanthrope)? I suppose as long as no Undead or Lycanthrope figure gets a power that excludes special powers on other cards it will be all ok here.
Now that
@
NecroBlade
(g'day mate), has brought up Agent Carr. Maybe using that wording would be better?
HUNTER’S ARSENAL
If Blade is attacking a figure within 3 clear sight spaces add 1 die to Blade's attack. Or if Blade is attacking an adjacent figure add 2 dice to Blade's attack.
Either way you are missing "clear" from your power.
