The Great Spirit's Awakening

You may look at the top card of your library any
time, and you may play lands from the top of
your library.
----------------------------------------------------------
I, II, III - You may play an additional land this
turn.
----------------------------------------------------------
IV - Put X +1/+1 counters on target land you
control, where X is the number of differently
named lands you control. It becomes a 0/0
Elemental creature with haste that's still a land.
