Oh, I forgot about Quick Attack; I'll probably add that to its moveset (Quick Attack on Sceptile saved me against a Focus Sash Cloyster Shell Smash sweep).
And I think I want to keep Steel Wing, although that's where the, 'Stay in, damage something then die.' meets the, 'U-Turn out.'. Tailwind also seems like a good option when near fainting.
I'll think about that. Thanks, everyone, for the tips.
