In this game, I name a pokemon with a specific type. Then you name a pokemon with its weakness and that begins with the last pokemon's last letter.
Example: Gloom (grass type)
Example: Magcargo (gloom's weakness and it starts with glooms last letter)
If there is no pokemon that has the same last letter of the other pokemon, and is its weakness, then the person who couldn't do it, will have to ask a trivia question about pokemon. The first person who answers the question correctly will get to pick the next pokemon.
Example: Onix (no pokemon begins with letter x that has onix's weakness) person that can not do it will ask a question and first person who answers it right will get to pick the next pokemon.
