Swords Dance will boost Farfetch’d’s attack stat. Brave Bird is Farfetch’d’s most powerful move, and Leaf Blade gives you an edge over Rock type Pokémon. Quick Attack enables Farfetch’d to take out weakened opponents before the opponent will KO Farfetch’d (which is probably going to happen).

All in all, you might not want to try Farfetch’d out. Its not one of the best Pokémon (in fact it is probably one of the worst).
