Floater

Floaters are Monster Cards that have replaced themselves in some way, allowing the player using them to generate card advantage. An example of a Floater is "Dekoichi the Battlechanted Locomotive." Because Dekoichi allows the player to draw a card, it has essentially replaced itself in the player's hand, losing the player no cards overall if it's destroyed or lost. Another example is "Gravekeeper's Spy." Spy replaces itself with a Monster on the field, as opposed to a card in hand, but the idea is the same; the player loses no overall card presence, even if the Floater is destroyed. Cards like "Old Vindictive Magician" and the Monarchs could be considered Floaters, since they generate card advantage as well. In general usage however, a Floater is considered to be a Monster that gains the player using it card presence.
