Oa, Black God of Enterprise

Ward—Discard a card with the greatest mana
value among cards in your hand. Oa's controller
creates an amount of Treasure tokens equal to
the mana value of the discarded card.
As long as your devotion to black is less than
seven, Oa isn't a creature.
Whenever an artifact or a legendary permanent
you control deals damage to a player, create that
many Treasure tokens. Whenever a permanent
you control dies, each opponent loses 1 life
and you gain 1 life.
