When building your first competitive deck, start with a strong main attacker or a powerful Pokémon V/VMAX/VSTAR. Then, add supporting Pokémon that complement its strategy, such as those that draw cards or accelerate energy. Include a robust Trainer card line-up (Supporters, Items, Stadiums) to ensure consistency. Aim for a balance of Pokémon, Energy, and Trainer cards, typically around 10-15 Energy, 15-20 Pokémon, and 25-30 Trainers.
