Flute of Shame

{t}: Add {c} or {b}.
{2}{b}, {t}, Exile a card from your graveyard:
Each other player reveals a card from their hand.
If any player's revealed card shares a type with
the exiled card, put both cards on the bottom of
their owners' libraries, that player loses 3 life,
and you gain 3 life. Otherwise, put the exiled
card on top of your library and each player loses
1 life. Activate only as a sorcery. (Players reveal
their cards simultaneously.)
