Deathtouch, wither

At the beginning of your end step, exile the top two cards
of your library. Until the end of your next turn, you may
play those cards.

Whenever you play a card from exile, create a Treasure
token. If you would create one or more Treasure tokens,
create that many plus one instead.

Whenever you sacrifice a Treasure, each opponent loses 1
life and you gain 1 life.
