Ponder; The Demon of Choice

When Ponder enters the battlefield you may
return a multi-modal card from your graveyard
to your hand. When you cast a multi-modal
card each other player may choose one mode for
themselves. You may select an additional mode
from that card for each player that chose the
same mode.
{g}{r}{u}: Each player may select a card from their graveyard and exile cards from their library equal to its mana cost. They may then place it on top their
library.
