Primal Groudon EX

Whenever Primal Groudon EX attacks, exile
the top card of each player's library, then you
may cast any number of nonland cards exiled
this way without paying their mana costs.

Groudon is said to be the personification of the
land itself. Legends tell of its many clashes against Kyogre, as each sought to gain the power
of nature.
