not completely sold, unless you're going to attach an energy to the leavanny itself and possibly fall an attachment behind and hope not to run into anything fire i'm not going to want to play this guy. not the worst card ever but i'm not down for putting five cards of it into my deck.

what did lucario gl do? i played it in every deck that could take advantage of type weakness. 1 0 1 is too thin a line to play with catcher roaming around.
Wait, why would I attach it to Leavanny? I'm confused. I'm thinking in decks such as Tyranitar, Blastoise, Cobalion, Gothitelle, etc. - cards like those that are at the mercy of their bad single type advantages (Donphan, Zekrom, Reshiram, Mew respectively) can gain a significant equalizer if they have 1-2 turns of no weaknesses. Okay, sure, have them Catcher up a Leavanny if they want to, but that's 1 extra turn the player can manage to keep attacking, and for decks that face pretty horrible matchups, it can be pretty crucial.
Of course, I'm not saying that Leavanny will become a super-tech in all decks overnight, but I would argue it's pretty valuable in decks that could use the (albeit many times) temporary weakness elimination.
ADDENDUM: I do want to mention Elekid's KGL article,
'Kay Good Luck', as an excellent example of a deck that can perform magnificently with a temporary weakness removal:
Where this guy really shines however is the Poke-Body. Its Body makes it so that none of your Pokemon have any Weaknesses. This solves so many problems that the deck had before. I was always a little bit paranoid about running into that random Jumpluff or Tangrowth deck, and against that 1 Bubble Coat really just won't cut it. However now that I've added in Exploud all those Grass decks are incredibly easy to beat. This also solves the big problem I had which was Luxray with an Expert Belt and 3 Energies doing Trash Bolt for exactly 180 damage. Bubble Coat usually worked for that, but in some cases it was hard to get it out or they would just do psychic restore or something like that to get rid of it. So Exploud makes it so that Luxchomp literally can't knock out KGL in one hit. Of course they can always drag it up or snipe it or something, but while they're doing that say Bye-Bye to 10 cards off the top of their deck
Decks that had difficulty (such as the Legends) can start to be interesting rogue combinations now because of Leavanny. Okay, yeah, it's not as good as Exploud, but it's Ability can't get shut down either, and the setup for many decks right now aren't at the same level as SP (yet, mayhap).

Agree with everything except yanmega.
Edit: You meant FINDING their weaknesses. I agree with that one.
Sorry, my mistake. Late night, papers and all. You understand
