Whenever an opponent discards a card, exile it from their graveyard with a stash counter on it. During your turn, you may play cards you don't own with stash counters on them from exile, and mana of any type can be spent to cast those spells. {3}{B}, {T}: Each opponent discards a card. Activate only as a sorcery.

{T}: Add {C}. {2}, {T}: Each player draws a card, then discards a card.

{T}: Add {C}{C}.

You may pay {B} rather than pay this spell's mana cost if there are thirteen or more creatures on the battlefield. Each player sacrifices thirteen creatures of their choice.
