Black and White change the way you earn experience: the formula rewards low-level Pokémon that beat stronger opponents. Combined with the right wild Pokémon and the right items, this lets you level up very fast. As for money, Unova is full of generous trainers to battle every day. Here are the best methods.
The principle of the fifth generation: the experience gained depends on the level gap. A level 20 Pokémon that defeats a level 30 opponent gains much more than a level 40 Pokémon defeating the same opponent. Lagging Pokémon therefore catch up with the rest of the team quickly.
Practical consequence: no need to over-train a single Pokémon. Rotate your team and give the Lucky Egg to the weakest one.
