Midnight Migration

Look at the top five cards of your library. You may reveal a land card from among them and put it into
your hand. Put the rest on the bottom of your
library in any order.
Dream {1}{g} (You may cast this card for its dream
cost. If you do, it gains flash. Dream only on your opponents turn.)
If you cast Midnight Migration for its dream cost,
look at the top seven cards instead.
