the only thing that Lucario can really set up on is Latias (I don't see Salamence using Stone Edge too much), which isn't really something that it will want to be setting up on until it is sure he only has dragon Pulse
When was it implied that i didn't read the discussion that occured below the suggestion? I was just making clear the advantages of having Scarfzone as opposed
to a Life Orb set.
Lucario is indeed a threat to this team should Magnezone be anything but a Scarf set. Yes Lucario can't set up a SD easily on this team but just think of the predictions Tay will be forced to do in order to work around it.
A common scenario would be Lucario getting in after a kill by say Heatran (should his opponent know he is not scarfed). SR is already down. Tay can either let Heatran in on a predicted SD and finish Lucario, meaning there's the risk of losing Heatran a valuable member, or switch out to Salamence that would take over 50% damage assuming both SR and Close Combat damage, rendering his backup counter to luke useless the next time a similar scenario occurs.
And the same scenario can occur with not just Heatran, but with also Scizor should it be at 70%ish and LO Magnezone.
