Remember to balance your team with Pokémon that can learn essential HMs like Cut, Fly, Surf, Strength, and Rock Smash without compromising their battle effectiveness too much.
While Johto lacks the early-game abundance of Wingull found in Pokemon Emerald, snagging a Wooper provides the essential Water and Ground coverage needed for the first few gyms.
While Pokémon Crystal relies on permanent team synergy to overcome gyms, Pokemon TCG Live focuses on rapid deck rotation to adapt to an ever-evolving competitive meta.
