Xynthar

A deck can have any number of cards named
Xynthar. On your upkeep step Xynthar deals 1
damage to each opponent, and one of their
creatures (of their choice).
If you control six or more Xynthar:
— {p/g}, {t}: Add {b/g}{b/g} to your mana pool.
— {x}, {t}: You gain life equal to half of X,
rounded up.
— {5}, {t}: Put target creature from a
graveyard to the top of your library.
