Quinn, The First Blade

Forbidden (This card starts the game in exile.)
Whenever an opponent mills or discards one or
more cards, you may cast this card from exile
until end of turn.
Ingest
When Quinn dies, you may exile it instead. If
you do, you may cast a spell from among face-up
cards your opponents own in exile without
paying its mana cost.
Beware the unknowable.
