Goblin Assailant

A vanilla 2/2 for two mana is the flattest thing a creature can be, and that is precisely the design purpose it serves. This is a filler common: the baseline body against which every ability, every keyword, every point of stats above vanilla gets priced. Its job is to be present in a Goblin's clothes, to give a red aggro shell a body that trades and attacks without asking anything of the deck around it, and to fill out a curve at the cheapest rarity. The Goblin Warrior line does light tribal work, but nothing on the card leans on it. Cards like this exist so the interesting cards have something to compare against; a designer needs the reference point of "2/2 for two, no text" to know what a mana dork, a hatebear, or a two-power one-drop is actually worth. Reasonable as generic aggressive filler in the most casual builds, invisible everywhere the format has better twos to offer.
