Dialga

Flying

Exile Dialga: Take an extra turn after this one. Activate this ability only as a sorcery.

Brilliant Diamond - If your life total would be
reduced to less than 1, instead shuffle Dialga into
your library and your life total becomes 4. Then
each player untaps all lands they control and
returns all creature cards in their graveyard that
were put there from the battlefield this turn.
