Sarin Hoerstwood

Deathtouch, Haste, Double strike
Whenever Sarin Hoerstwood deals combat
damage to a player, that player gets a poison
counter. (Players with ten or more poison
counters lose the game.) At the beginning
of your upkeep, if Sarin Hoerstwood has dealt
combat damage to a player this turn, you may
search your library for an artifact card, reveal it,
put it into your hand, then shuffle your library.
The arm is artifical, but they are a natural.
