What is a token creature in Magic The Gathering?

Tokens. There are certain creatures that are represented by tokens, called Creature Tokens, these are treated the same as creatures. Tokens in a game are often represented by a facedown card or there are also token creatures such as soldier.

How do token creatures work?

Tokens can only exist on the battlefield, not in your deck, graveyard, or hand, so when they're destroyed or anything else happens to them, they simply "disappear" ( and you usually put the token card to one side or in a box ).

Do tokens count as creatures?

Yup. Tokens behave just like regular creatures in every way, except that they cease to exist when they leave play.

Do tokens go to the graveyard magic?

A: Tokens go to the graveyard as regular creatures, and are removed as a "state-based effect" when a player gets priority again. They stay in the graveyard long enough to trigger abilities, like the one of Soulcatchers' Aerie, before they are removed.
