Esfuerzo coordinado

Encantamiento, 2WW (4)
Al comienzo del mantenimiento de cada jugador, todas las criaturas que controlas ganan la habilidad de volar hasta el final del turno si una criatura que controlas vuela. Lo mismo vale para las habilidades de inspirar temor, dañar primero, dañar dos veces, cruzar tierras, protección, arrollar y vigilancia.
Illus. Michael Sutfin

Enchantment
At the beginning of each upkeep, all creatures you control gain flying until end of turn if a creature you control has flying. The same is true for fear, first strike, double strike, landwalk, protection, trample, and vigilance.¹

Gatherer Card Rulings [Nov 2009]

• 10/1/2005: For example, a player controls three creatures when Concerted Effort's ability resolves: one creature with flying and protection from red, one with islandwalk and protection from green; and one with vigilance. All three creatures will have flying, islandwalk, vigilance, protection from red, and protection from green until the end of the turn.
• 10/1/2005: Creatures keep all abilities granted this way until the end of the turn, even if Concerted Effort or the original creature with that ability leaves the battlefield.
• 5/1/2006: In Two-Headed Giant, triggers only once per upkeep, not once for each player.
