The Giant

Vigilance, trample, hexproof
Escape - {7}{g}{g}{g}, Exile eight other cards from
your graveyard. (You may cast this card from
your graveyard for its escape cost.) The Giant
escapes with seven +1/+1 counters on it. When
it enters the battlefield this way, each opponent
sacrifices a non-Giant creature, sacrifices a land,
and discards a card.
