Mega Staraptor

This Staraptor is built almost entirely around HP and Speed rather than Attack, since it doesn't have a boosting move of its own and isn't expected to score one-hit knockouts. Its job is to set Tailwind, stick around thanks to Intimidate's damage reduction combined with Sinistcha's healing, and clean up games once earlier attackers have already secured knockouts. Jolly with max Speed lets it reliably move first to set that Tailwind before the opponent can respond.
