Celebi Only

The strategy is to use a Caterpie to bring out the rest of the Pokémon. The second Caterpie is just a backup or to be sacrificed if more time is needed to place counters on Celebi. The blue cards are mainly to protect Caterpie, along with the potions, to heal it and hold out while Celebi gathers enough counters. If Celebi happens to appear as the first card, the strategy is simply to stack counters on it and heal it as much as possible. If it can’t hold out and there’s a Caterpie available, it’s better to switch to Caterpie to buy some time to heal Celebi.
