Object

Object is a rules term, representing a 'single object'.

Details
Although a game of Duel Masters is played using cards, not all objects in the game are represented by a single card.

For example, an evolution creature is treated as a "creature", but also as "multiple cards". However, it is clearly distinguished from being just a single card due to the evolution source card.
