Pokémon Ghost

[TreyofHearts]

I've chosen a letter: G. Now, compound upon it in pursuit of a word without spelling the name of a Pokémon. Whosoever turn it is can challenge the previous player to prove that the word is a Pokémon, but if they can't, then the current player loses. Whoever loses earns a letter from the word "Ghost" and signs themselves with it in-post. Whoever spells out "Ghost" first loses. Rinse and repeat.
