闇(やみ)の暗(あん)示(じ)

Each opponent sacrifices a creature or planeswalker of their choice, then discards a card. You return a creature or planeswalker card from your graveyard to your hand, then draw a card.

When you cast a Bolas planeswalker spell, exile this card from your graveyard. That planeswalker enters with an additional loyalty counter on it.
