I apologize, but there doesn't appear to be any GBA game called "Monster Summoner". There are games with similar titles, such as "Summon Night: Swordcraft Story" and "Yu-Gi-Oh! The Sacred Cards", which feature elements of monster summoning. If you can provide more information or clarify the title of the game, I would be happy to try and assist you further.
