Nature's Embrace

Most Auras commit to a single kind of target the moment you decide to run them; this one refuses the choice, folding a creature buff and a land upgrade into one targeting clause and letting the board state at cast time pick which card you have. Point it at a creature and it is a Rancor-shaped stat pump. Point it at a land and that land gains a repeatable tap ability for two mana of any one color, which is real color fixing wearing green's clothes. The insurance is in the targeting itself: if the only creature you would want to buff is gone or too risky to invest in, you still have a legal home that produces mana instead of a dead card in hand. Neither half is pushed on rate. A three-mana +2/+2 is below the going price for a pure buff, and a permanent that only lets one land make two mana is unremarkable measured against dedicated ramp. The design lives in the seam between the two, in never having to lock in at deckbuilding which card this is. That is the same hedge that later modal double-faced cards sell as a headline mechanic, reached here through the older and humbler route of "enchant creature or land," a target line broad enough to make one Aura do two unrelated jobs depending on where you point it.
