Is the lair considered to be the card of the place it copies?
Example: I have no discard pile, I play Lair and have it resolve. The creature token is on the Jungle. Since I have no discard pile to take back, I instead choose to copy the place of the creature token. Since the Jungle says take back "this" card and a card from your discard pile. Do i consider the Lair as "this" card and take it back to my hand or it only applies to the Jungle card and thus, I have a wasted Lair card in my discard pile when we move to phase 4?
I felt that you wouldn't be able to just get back the Lair in your hand when you copy the Jungle or even the Swamp.
Indeed the copy the power of a place and becomes this place. If you copy the Jungle, the Lair becomes "this card" and you take it back plus 1 card from your discard pile.
Apply the same rule with the Swamp.
