Siempre que una criatura que controlas haga daño de combate a un jugador, pon un contador +1/+1 sobre esa criatura.
Aprender la habilidad — Las criaturas que controlas con contadores +1/+1 sobre ellas tienen las habilidades de alcance y arrollar.
Once a creature that has reach because of Sphere Grid's last ability has blocked a creature, removing all +1/+1 counters from that creature or causing Sphere Grid to leave the battlefield won't cause that creature to stop blocking.
