<p>Toxic is an interesting option, and can be used in place of Brave Bird, though it will make Skarmory complete Taunt bait. Surprisingly, Skarmory has access to some boosting moves such as Curse, Swords Dance, and Agility, which are sadly wasted on Skarmory, as it has neither the stats nor the movepool to utilize them effectively. If the recoil damage from Brave Bird proves to be troublesome, Drill Peck is a safer, albeit weaker option.</p>
<p>Counter is another viable move, as Skarmory takes physical hits well, and can help net a surprise KO. However, once used, it loses much of its value in its surprise factor. Skarmory can also set up Stealth Rock, though this would mean having to forgo Spikes.
