The two people that got it right first were Bboy4life and.......game_wiz! The trios I was thinking of were Zapdos, Moltres, Articuno; Raikou, Entei, Suicune; and Azelf, Uxie and Mesprit. Other Pokemon such as Rayquaza, Groudon, and Kyogre aren't considered a trio in my book. The ones I listed all have appearance in common. Legendary birds, dogs.... I will update scores later.
What Pokemon do you think is the least useful and why? Points determined on answer.
