Carnivorous Canopy

Green's usual answer to noncreature threats is the naturalize effect: a one-for-one trade that destroys an artifact or enchantment, occasionally both types on the same card, and asks nothing more of you. This one widens the target to a third category (creatures with flying, the axis green struggles most to reach from the ground) and then bolts a reward onto hitting something cheap: destroy any legal target and, if its mana value was three or less, you proliferate. That rider reframes what the card is for. In a deck with no counters to grow, it is flexible interaction that happens to answer fliers. In a deck built on counters (poison, +1/+1, charge, loyalty, the whole proliferate lattice), the destruction is nearly the pretext and the proliferate is the payoff you spent green mana to buy. The mana-value gate rewards aiming at a cheap target, clearing a small blocker or a mana rock, but proliferate scales best once your counters are already advanced. It is a single targeted removal spell with a conditional rider, not a choose-one modal card; the second half only fires if you both aimed low and built to care. That is a cleaner shape than green usually earns when it borrows the proliferate identity that white and black were built around.
