Sylvan Shepherd

This is the d20 die-roll mechanic doing its most modest work: attaching a randomized lifegain trigger to a body that was already asked to attack. The roll table is generous in only one direction, and even the jackpot (five life on a natural 20) barely moves a game's clock; the vast majority of swings hand over one or two life, which is closer to incidental upkeep than a payoff. What makes the design coherent is the pairing of vigilance with an attack trigger: the card wants to swing every turn without exposing itself on defense, so the lifegain accrues turn after turn while the 2/3 stays home to block. That is the whole engine, and it is deliberately small. The die roll here is flavor scaffolding first and mechanic second, a way to fold tabletop dice-rolling into a creature that would otherwise read as a plain lifegain Druid. It exists for decks that count lifegain triggers as events rather than as raw life totals, where the number rolled matters less than the fact that a number got rolled at all.
