Attuned Hunter

Green rarely gets to reward graveyard interaction directly, because green's relationship with the graveyard has mostly run one way: it fills the yard and mills, but the payoff cards live in black or the delve mechanic. This flips the trigger. Rather than caring about cards entering the graveyard, it grows every time cards leave yours during your turn, which quietly rewards the exact things green already wants to do: cast a delve spell, escape a threat, flash back a value spell, or recur a creature with a self-mill package underneath it. The clause counts a batch as one event, so a single mass-exile like a large delve payment nets one counter rather than many; the incentive is to trigger on multiple turns, not to dump the graveyard all at once. The trample matters more than the modest starting body suggests, since a counter or two turns it from a body that trades into one that pushes damage through chump blockers on the same turn you're already fueling it. What holds it together is the "during your turn" restriction: it won't grow off opposing graveyard hate or an opponent's exile effects that resolve on their own turn, keeping the reward tied to your own turn rather than passive accumulation across the whole game.
