Phantom Beasts

From Yu-Gi-Oh!

Phantom Beasts are a series of Beast-Warrior Type monster cards whose name includes Phantom Beast. In the TCG, two of these monsters - Gazelle the King of Mythical Beasts and Chimera the Flying Mythical Beast are included as Phantom Beasts, as their OCG names have "Phantom Beast" in them instead of "Mythical Beast(s)". Their effects for the most part affect other "Phantom Beast" monsters, and for the most part work when the activated monster card is sent to or in the graveyard. They're what the effects of the White Knight monsters, used by Chazz Princeton, are based on.
