If its your starter than play 3-4. Some people say Phione/Call replaces Pachi, IMO it depends on the deck. (example: I play Pachi in my TogeChomp deck for three reasons: 1. I need 3 basic pokemon: Gible, Togepi, and Baltoy. 2: Playing Call is suicide since Call turns off Chomp's Bady. 3. Call will take up too much energy space since Togekiss can only get basic energy.)
