Serpent Cult Assassin

Deathtouch
{1}{b/g}{t}: Target creature gains Deathtouch until
end of turn.
Adamant(If {b}{b}{b} was spent to cast Serpent
Cult Assassin it gains Infect.)
The elite assassins of the Serpent Cult are silent and
stealthy, elusive and secretive, and as deadly as an
adder's venom, and often as bitter.
