Alvela, Cunning Confidant

Skulk, Ward {3}
Whenever a creature dies, surveil 2.
Whenever Alvela deals combat damage to a
player, that player reveals their hand. You may
exile a noncreature, nonland card from among
cards revealed this way, or from your graveyard
and copy it. You may cast the copy for as long as
it remains exiled using mana as though it were
mana of any color.
