Tergrid, God of Fright // Tergrid's Lantern

If you put an Aura onto the battlefield using Tergrid's ability, you choose what the Aura will enchant just before it enters the battlefield. An Aura put onto the battlefield this way doesn't target the player or permanent it will enchant, so permanents or players with hexproof may be chosen; however, the chosen recipient must be able to legally be enchanted by the Aura, so a player or permanent with protection from one of the Aura's qualities can't be chosen this way. If there's nothing legal for the Aura to enchant, it stays in the graveyard.

If an opponent sacrifices a nontoken permanent, it doesn't matter which graveyard it goes to. Tergrid's ability will trigger.

If an effect allows you to play a land or cast a spell from among a group of cards, you may play or cast a modal double-faced card with any face that fits the criteria of that effect.
