>>22087817I know setting up in doubles is always difficult, but honestly running Hyper Voice/HP Fire/Sub/Calm Mind works pretty damn well, especially if the rest of your team can keep the pressure on enough that they can't risk ignoring them.
Otherwise, fire types are what you're seriously struggling with, I'd be tempted by HP Rock instead of fire, then Shadow Ball for Aegislash. If it's in a metagame where Heatran is allowed, HP Ground would be great too, depending on what the rest of your team struggles with.
