Haste, Protection from Deathtouch, Infect, and
Wither
This creature gains +2/+2 until end of turn if
it is fighting, blocking or being blocked by a
creature with infect, wither, or deathtouch, and
all damage dealt by that creature is negated.
"Seviper's only enemy. It is completely immune to the creature's toxins, and, in fact, gains strengths from whatever poison is injected into its veins."
