Elder Awakening

Cumulative upkeep - Put the top card of your
library into your graveyard, then, if a land card
was put into your graveyard this way, repeat this
process.
When you sacrifice Elder Awakening, search
your library for a creature card with converted
mana cost equal to the number of age counters
on Elder Awakening, put it onto the battlefield,
then shuffle your library. It gains haste until end
of turn.
