The Boulder, Ready to Rumble

Earthbend is a keyword that manufactures a creature out of your mana base rather than pumping something already on the board, and this is the payoff that closes the loop on itself. The attack trigger counts creatures you control with power 4 or greater, and the 4/4 body qualifies for its own tally, so the very first swing earthbends for at least one. Every large threat you add widens the next trigger, and because the animated land arrives carrying counters, it can climb past the power-4 line and start feeding the count on future combats. That recursion clause is what makes stacking counters on a fragile 0/0 worth it: kill the land or exile it, and it returns to the battlefield tapped, so removal buys a tempo swing at best rather than a clean answer. The reward structure pushes green toward a handful of individually fat bodies instead of a token swarm, since only creatures that reach power 4 advance the trigger at all. Note the timing wrinkle: the trigger fires on attack, after declare-attackers has passed, so the freshly animated land cannot join the current assault; the haste and the counters are an investment in the following turn, when that promoted land becomes another qualifying attacker and folds back into the count. It is a midrange engine that treats lands as reserve creatures and creatures as fuel for animating more of them, ramping into beatdown that compounds as the board grows.
