Forestwalk is the most matchup-dependent evasion ability in the game: it slips an attacker past every blocker when the defending player controls a Forest, and does nothing at all when they do not. What this little Dryad does is detach that keyword from the creature that owns it and turn it into a repeatable grant, handed out at will to whatever attacker needs to get through. The cost is steep relative to the payoff: a tap and a 1/2 body's worth of board presence spent on an effect that is blank against half the field. Against a blue-white control deck it sits there as a 1/2 with no relevant text. Against a green-heavy opponent it ushers a fatty through unblocked, every turn, indefinitely. That swing, between dead weight and a soft lockout, explains why a repeatable, color-keyed evasion grant lives at the lower rarities: it is the narrow, flavor-forward tool a designer reaches for when filling out a green slot. The Shaman framing fits an era fond of giving Dryads and forest-spirits abilities that bend the woodland itself to a creature's purpose, and there is something coherent about a forest-spirit teaching an ally to walk unseen through trees. As repeatable evasion it is real, but it asks the format to cooperate by being green, and the table rarely obliges.
