Every Pokemon trainer listen up. If you use a lot of high retreat
pokemon like Charizard, Blastoise, Snorlax, etc., then 4 switches are a must,
especially for low energy decks. If your dealing with an active Pokemon with
lots of damage counters on it, I always use a Switch and a Mr. Fuji for extra
insurance against Gust of Winds. That way you can get some extra energies
back into your deck. but still keep thne Pokemon.
