Honedge is a great Litte Cup Pokémon, with few weaknesses and very viable resistances and immunities, walling previous beasts in the tier, and striking back with amazing power, with it's great movepool. But like you said, his SpD may ruin him, so throw on an Assault Vest to take away that weakness.
Shadow Sneak: STAB Priority is always great.
Sacred Sword: Covers normal and dark types.
Shadow Claw: STAB, good power, 100% acc, high crit rate, what more could you ask?
Iron Head: STAB and chance to flinch.
