I know Ninja Spirit is nasty on bridges. You don't actually stand on the bridge yourself. You just wait for someone stupid to cross one, then spam shurikens at them until they drop. There's a reason why a carat exo is still popular with moonlight junkies.
Thunderstorm Charger can stun someone long enough for you to push them off. Same with Fire Charger if you get someone with Firewall. They both usually have to be close range to be effective for edging though and smarter players won't fall for it much. Don't expect to live too long next match if you spam Thunderstorm in team games either...you'll be like the first person they hunt down lol.
