Transcend into Nothing

As an additional cost to cast Transcend into Nothing, reveal a white card, a blue card, a black card, a red card, and a green card from your hand.
You can't cast spells.
Discard a card that shares a color or converted mana cost with the top card of your graveyard: If you have no cards in hand and no cards in your library, you win the game. Otherwise, draw a card.
