Celshu, Untouchable Counsel

Deathtouch
The first time each turn that you dredge, you
may choose one of the cards that you mill for
that ability. If you do, put that card on the
bottom of your library, then you gain 1 life
and create a Treasure token.
Mill two cards: Celshu gains hexproof until
end of turn. You lose 4 life. Activate only
once per turn.
