Earth Surge
An anthem with a clause so narrow it does nothing on an ordinary board: a flat +2/+2 to creatures would be a generic green effect, but restricting the bonus to lands-that-are-creatures turns a routine pump into a build-around. The strategy it supports has to exist before the card matters at all. The wrinkle is that the buff is continuous and conditional rather than triggered, so the enchantment quietly tracks the animation state of the whole board: a land that becomes a creature this turn is immediately bigger, and a land that stops being one simply drops the bonus. It is also symmetrical. Every land that is a creature gets the +2/+2, including an opponent's animated manabase, which makes it a strange card to deploy into a mirror of the niche it serves. Two copies stack, and combined with effects that animate every land at once the math escalates quickly, but the plan is fragile in the way most lands-matter combat is: a single board wipe punishes the entire investment, and the enchantment contributes nothing until the lands stand up. That conditionality is the whole design. It is written for a deck committed to animating its manabase, a green-leaning curiosity that has to commit to the bit before the card earns its slot, with the symmetry as a quiet reminder that the effect was never really yours alone.
