Dungeon Masters Idea for a Pokemon related game!

Here is an idea for a game that is similar to Pokemon. There are eight dungeons. Each with a Dungeon Master(like a Gym leader). The player will have a fairy to talk for him/her and to help them. In the Dungeon, the player can find items to permanently increase their party of monsters' stats,  find items, and battle monsters encounter in the Dungeon. When the player defeat a Dungeon Master, the player receives an item to teach his/her monster a move, and a story item the player have to collect. A Dungeon can be found in towns for the player to explore.
