Dragon Collection

well both anime are about a boy who gets trapped inside a world where they have always wanted to be. in mar he dreamed of this world. in dragon collection it is a popular game he always wanted to try out. both are great anime. and the protagonist is extremely strong. and have a rare monster. 

Main characters are transported to another world. Fire-kun and Hiro have the same personality, same monster deck, and guts. Similar monsters from both series pop up. Such as Blaze Knight, and Fire Drake. Fire drake from Dragon Collection and Kerogon have the same voice actor. Both are fire type monsters too. Also Pandora and Monster pot help guide our main characters throughout the series. Hiro and Fire-kun go on adventures with their comrades and save the world from an all powerful evil force.  

Dragon Collection is Pokemon in disguise. Hiro is Ash, the dragon pup is Pikachu, cards are balls, Green Pepper Gang's Meatmania is Team Rocket. 

Fun, lighthearted anime involving card battles, although battles in Dragon Collection aren't played like a structured TCG. Both have very cute art styles, likeable characters and are very funny.
