Llanowar Reborn

Graft on a land is a strange grafting of two ideas that almost never share a card: mana production and counter distribution. Most graft sources are creatures that hand out their own counters as they shrink, paying for the gift with their own body. Here the counter lives on a land that taps for green and otherwise asks nothing of you, so the +1/+1 it carries is pure upside waiting for the next creature to walk onto the battlefield. The tradeoff is baked into the entry-tapped clause: a land that does this much can't also come online the turn you play it. The single counter never refills, which keeps it from snowballing; it is one bonus, paid out once, to whichever creature you most want to grow. That makes it a quiet enabler in any deck that cares about counters as a resource: modify-matters strategies, evolve and proliferate shells, anything that wants a fresh creature handed a counter shortly after it arrives. The design's real cleverness is putting the graft trigger somewhere it can't die in combat or be answered by removal, so the counter is far more likely to actually land than it would be on a creature offering the same deal.
