Aegon, the Loyal

When Aegon attacks, look at defending
player's hand. You may pay {1}{b}. If you do,
defending player discards target card and you
lose 2 life.
{1}{u}{b}, Sacrifice a creature: Exile a card
from a graveyard. For as long as it remains
exiled, you may cast it and you may spend
mana of any color to cast it.
