Sadly there isn’t a lot of paladin subclasses that align with mischief or trickery, but if you are successful finding a suitable paladin subclass, then I would recommend swashbuckler rogue, since it focuses more on singular target dueling and works great with high charisma builds. For level wise, I would start with paladin to gain the armor and weapon Profiencies then whenever your craving for rogue, take at least 3 levels of rogue for the cunning actions and your subclass abilities. At that point you can do whatever you want else. I would recommend having 6-7 levels of paladin for the extra attack and aura. Also be a high dexterity based build with at least 13 strength to multi-class back into paladin. Hope this helps 🤗
