Varuk, Gravecaller Shaman

Whenever you cast a a creature spell, draw a card.
If your graveyard contains five or more creature cards, instead draw two cards and discard one card.
{1}{u}{g}, {t}: Exile a creature card from your graveyard.
Then, return a creature card from any graveyard to the battlefield under your control. It gains haste. Sacrifice it
at the beginning of your next end step unless a creature
died this turn.
