Encantamiento
Siempre que pongas uno o más contadores sobre un permanente o jugador, Todos serán uno hace esa misma cantidad de daño al oponente o a la criatura o planeswalker objetivo que controla un oponente.
All Will Be One's ability will trigger any time you put one or more counters on a permanent or player. This might be due to a spell or ability resolving, a permanent you control entering the battlefield with counters, or combat damage from a source with toxic, infect, or wither.
If more than one creature with toxic deals combat damage to a player at the same time, those counters are placed as a single event, and the ability triggers one time.
