Encantamiento — Aura
Encantar criatura.
Cuando la Posesión desértica entre al campo de batalla, si controlas un Desierto o hay una carta de Desierto en tu cementerio, ganas 3 vidas.
La criatura encantada no puede atacar ni bloquear y no pueden activarse sus habilidades activadas.
For abilities that trigger only if you control a Desert or there is a Desert card in your graveyard, one condition must be true as the ability triggers and one must be true as the ability resolves. They don’t have to be the same condition, though. For example, you could sacrifice your only Desert after the ability triggers but before it has resolved.
