請問一下這兩張牌在維持階段的順序... - 魔法風雲會

一張是一點無色的神器

Myr Servitor
At the beginning of your unkeep, if Myr Servitor is in play,each player
returns all cards named Myr Servitor from his graveyard to play.

一張是二無一黑的生物結界牌

At the beginning of your unkeep, sacrifice a creature.
Enchanted creature gets +3/+3 and has trample.
Enchanted creature is a Demon Spirit.

當我場上有一隻秘耳貼上結界 我能先撿另一隻回場後再犧牲它嗎?

當我有兩隻秘耳,其中一隻貼了結界,另外一隻可以拿去犧牲後又撿回來嗎?

請高手大大幫忙,謝謝~
