Feitiço
Convergir — Ganhe o controle da criatura alvo se o poder dela for igual ou inferior ao número de cores de mana gasto para conjurar Exercer Influência.
Check the creature’s power as Exert Influence resolves to see if it’s less than or equal to the number of colors spent to cast Exert Influence. If it’s greater, Exert Influence will finish resolving with no effect.
