Mixed Blaziken and all blaziken sets want 216 Spe with a neutral nature to outspeed Scarfed Garchomp after 2 Speed Boosts.
Blaziken Analysis said:<p>Blaziken can also run either Hidden Power Electric or Hidden Power Grass instead of Hidden Power Ice to deal with bulky Water-types such as Quagsire, Jellicent and Slowbro. However, keep in mind that Slowbro and Quagsire is uncommon, and that in the absence of Hidden Power Ice, Pokemon like Gliscor, Landorus and Garchomp can pose problems for Blaziken.</p>
