Tel-Jilad Outrider

Protection from artifacts on a green body does the unglamorous defensive work the color rarely gets to do: it cannot be blocked or killed by an artifact creature, it walks past artifact-based removal aimed at it, and equipment cannot be moved onto it. The 3/1 frame is the price of that immunity. A green four-drop usually expects more toughness for its mana, and stapling a single point of toughness to the body means any non-artifact answer (a burn spell, a bounce, a creature with reach) erases it the moment it does. Note the limit of the keyword in combat: protection stops damage from the artifact source, but a non-artifact creature swinging a piece of equipment is itself the source of that damage, so a buffed flesh-and-blood blocker still trades with or kills the Outrider. This is a hate creature wearing a beater's clothes: aggressive enough to threaten an artifact-heavy opponent, fragile enough that it cannot just be jammed into any board. Protection is a static keyword that asks the controlling player to know exactly which half of the battlefield it is good against, and against a deck without artifacts the Outrider is simply a 3/1 that dies to a stiff breeze. It descends from the early tradition of protection-from-a-card-type creatures printed when a set's theme is loud enough to warrant a built-in counter; the narrower the metagame's artifact density, the wider the gap between this card's ceiling and its floor.
