“Warrior Master” Toy Line Idea

Plot: In the far future, on an alien planet called Heeltia, children play a card game called Warrior Master which pits real warriors from across the universe and time against each other. These are no ordinary playing cards, as these cards can summon the literal warrior into a battle. So, a medieval knight could fight a cowboy, a professional wrestler could battle a superhero, and a barbarian could brawl with a literal killing machine from another world. It may be a just a game to this alien children, but to the warriors, it’s life and death.
