"unboosted Jolly Tyrantrum Head Smash has about 96% of the power of a CB Terrakion Stone Edge, which is pretty amazing. With a Life Orb, Tyrantrum's Head Smash is powerful enough to 2HKO physically defensive Skarmory nearly 100% of the time with no prior damage. Assuming a set of Rock Polish / Head Smash / Dragon Claw / Earthquake, Scarf Latios, Thundurus-I, Tornadus-I, Thundurus-T, Hydreigon, Haxorus, Salamence, Gengar, Landorus-I, and Genesect are all OHKO'd. Scarf Terrakion and Garchomp can be OHKO'd at least part of the time, and a little prior damage will clinch it. Keldeo survives all of these attacks pretty easily, and while it can still be 2HKOd by Dragon Claw, it threatens to OHKO back with Hydro Pump. Overall, though, Jolly Life Orb Tyrantrum has a really good shot against most of those Scarf users."
