It's token time!
In Magic: The Gathering, some cards create new game objects, called tokens. Since they aren't part of your deck, you can use nearly anything to represent them - including custom print outs.
All of these tokens are ones that already exist in the game, save for two: Iofi and Irys. Nothing specifically creates tokens of their type. However, there are two cards that can create tokens of any valid creature type.
