who cares about ohkoing cressy with leav, they're never going to stay in on you anyways and if they do stay in on you you deal 75%+ (didnt both to calc but it's a lot) with stab and then get a slow sd passers out to your reciever because you move slower from the para. run lefties, sd pass usually doesn't care about status (except sleep. and there are no sleepers who can do anything to leav. and sd sub pass is good for other guys).
aero is a solid reciever for leav, so is scarf aggron, so are dragons (scarf gabite in particular seems like an awesome reciever from leav as it has those awesome stabs and can switch in on fire and rock moves). but when you're building a team with quickpass don't try to shove in a reciever which doesn't fit the team synergy, baton pass is an awesome move because it lets you scout the switch and send in the best response. give yourself a couple solid options to pass to depending on the situation without being useless if you can't pull off the pass.
leav itself looks pretty bad though because it has gaps in its coverage and it doesn't have enough defensive utility to consistently switch in, i can't see why i'd want to use it over a passer sawsbuck or something.
