Jungle Barrier

Wall of Blossoms answered the question for green years earlier: a 0/4 that draws a card the moment it lands, paying for itself while it stonewalls aggression. This design extends that template into two colors and adds two points of power and two of toughness, turning the cantrip-wall into a 2/6 that holds off almost anything red or white can field on the ground in the early turns. Defender is the cost that keeps the cantrip honest: you are buying a card and a roadblock, never a clock, and the four-mana price reflects that you are getting two effects rather than one. The catch is that the wall lives in green-blue, a color pair built around card advantage and stalling toward a payoff rather than racing, so the draw-on-entry rewards exactly the deck that wants a six-toughness blocker in the first place. It is a clean piece of two-color enabler design from an era defined by gold cards that pushed players to splash: the second color is not flavor, it is the reason this version of Wall of Blossoms exists at all, slotting the cantrip-wall into a control shell that already wanted the blue.
