Avacyn's Pilgrim

A green body that taps for white mana is the kind of fixing Selesnya decks have always wanted but rarely gotten at this rate: most one-mana dorks add the color that printed them, while this one bends the wheel the other way. The split matters because green and white sit at the start of the curve in their own colors, so a turn-one Pilgrim doesn't just ramp, it opens a second color a full turn earlier than a two-drop fixer would. The 1/1 body is the cost of that flexibility; it dies to anything and rarely blocks profitably, so the card lives entirely on the back of its mana ability. What makes it more durable than most early dorks of its era is the direction of the fixing: a green deck splashing white gets exactly the creature it needs to cast an early white removal spell or an off-color two-drop on curve, and a Human creature type quietly tucks it into tribal builds that care about the line. It is small, fragile, and deeply specialized, but in the narrow lane of green-into-white acceleration it does a job that almost nothing else at one mana does as cleanly.
