Well, I want to know which would be better, Primo's egg will give boosted exp, which will help in the grind that will happen throughout my can you beat Pokemon heartgold with only 1 mareep, but I still would like to hear your suggestions.
Primo's Pokemon do not get boosted experience unless you trade them to another player. There is no advantage to using his Wooper or Mareep unless your Pokemon are too weak to catch wild Pokemon or you can't afford Poke balls.
