Prototype creatures are creatures that are used to refer to an entire class of creatures with the same power and toughness and mana cost or converted mana cost (and in some cases, abilities). What makes these creature prototypical is their recurrence at common or uncommon rarity in almost all modern sets. Of these categories, Gray Ogres and Pikers are the most common (since they existed well before value bears became common) with nearly 400 and over 200 respectively.
In most cases, these are usually found with (often strong) upsides in the colors they are most common in. In most cases, multicolored cards are not considered to belong to the "corresponding" prototype.
