Ya it loses to Heatran (#12 lead) who also beats machamp (so many people run specs with overheat as their lead) and ya it loses to metagross but just use shuca tran. And how does it have ZERO late game use? it deals a fuckton to mence with fake out, outspeeds gengar and can even SWITCH IN TO IT (shadow ball obv) and hits it very hard with aerial ace, it hits celebi hard with fake out + aerial ace, deals a shitload to scarfgon, kos stallbreaking gliscor while surprising it (if you haven't used ice punch yet) fake out does a lot to kingdra and gyara, hits LOmie hard with fake out and can win speed tie and ko it with seed bomb, deals 27.5% - 32.7% to offensive cune with fake out and 49.7% - 58.5% with seed bomb. so thats... about 78 % minimum and about 92 % max so with rocks and some prior damage it revenges it with ease, also takes out non lead perts, revenges togekiss with ease, deals about 63 % minimum to zappy with fake out + ice punch which is a ko with rocks and some prior damage, revenges breloom, deals 58.8% - 69.9% to specs jolt with fakeout, revenges non vaccum wave/mach punch ape with ease, revenges heracross easily, does some damage to luke with fake out (albeit not that much, 25.6% - 29.9%, but every little bit helps) does 18.8% - 22.4% to sub empoleon (so if you use lucario on your team, which is a good idea because this lures gliscor and kos it with ice punch, a combination of priority kills it), revenges electivire (lol,) kos mixmence and mixnite with ice punch (outspeeding obviously) does a shitload to LO azelf, seed bomb does 50 - 60 to ttar without a boost and fake out does like 12%ish minimum, does 34.9% - 41.5% to tentacruel with fake out, and 35.4% - 41.8% with aerial ace, (like 70ish minimum and 83 max which is a lot with rocks) revenges so many frail scarfers...
so you were saying it has 0 use out of the lead spot? oh ok.
